โจ Texture & Feel
68%+ Rice Extract Concentration
Ultra-high concentration of Oryza Sativa delivers antioxidant-rich flavonoids and emollient proteins that nourish, soften, and gradually brighten skin using centuries-old Asian beauty tradition.
2% Niacinamide for Visible Brightening
Clinically studied Vitamin B3 at an effective concentration helps even skin tone, refine pores, strengthen the moisture barrier, and regulate sebum production without sensitizing skin.
Triple Humectant Hydration Complex
Glycerin (4โ6%), Betaine (2.7โ4%), and Arginine work in synergy to draw moisture from the environment into the deeper skin layers, maintaining intense hydration all night long.
Versatile 3-in-1 Formula
Use as an overnight sleeping mask, a 15-minute wash-off treatment, or a lightweight daily moisturizer morning and night. One jar, three powerful skincare roles.
๐ก๏ธ Safety & Compatibility
Contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreen filters. Niacinamide at 2% and rice extract are widely considered safe during pregnancy. Always consult your healthcare provider before adding new products to your routine.
Contains Elaeis Guineensis (Palm) Oil, Palm Kernel Oil, Helianthus Annuus Seed Oil, and fatty acid esters (Cetearyl Olivate, Sorbitan Olivate) that can feed Malassezia yeast. Not recommended if you have fungal acne or are Malassezia-sensitive.
Retinoid-free formula is completely safe to layer after retinol or prescription retinoids in your PM routine. Its soothing humectants and emollients help buffer any dryness or sensitivity caused by retinoid use.
No added fragrances, perfumes, essential oils, or common allergens. EWG Skin Deep rates this formula low concern for cancer, allergens, and developmental toxicity. Suitable for reactive and fragrance-intolerant skin.
Niacinamide is pH-flexible and stable โ it works well alongside AHAs, BHAs, and Vitamin C. Apply this mask as the final step after actives to seal in treatment benefits and restore moisture.
Contains Cetearyl Olivate and Sorbitan Olivate (Olivem 1000 emulsifier complex derived from olive oil). Those with known olive oil sensitivity should patch test on the inner forearm before full-face application.
๐ฌ Ingredient Breakdown
๐พ Oryza Sativa (Rice) Extract 68%+ Proven
The hero ingredient at an exceptional concentration, derived from Oryza sativa rice grains. Used for centuries across East and Southeast Asia for skin softening, brightening, and conditioning. At 68%+, it forms the primary aqueous base of this formula rather than a mere marketing addition.
- Antioxidant protection: Rich in flavonoids, ferulic acid, and Vitamin E that neutralize skin-damaging free radicals and help delay visible aging.
- Brightening mechanism: In-vitro studies show rice water inhibits tyrosinase enzyme activity, gradually reducing melanin production and fading dark spots over consistent use.
- Barrier support: A 2002 clinical study found rice baths improved skin barrier function and accelerated wound healing in patients with atopic dermatitis.
- Emollient action: Proteins in rice form a protective, moisture-trapping film on the skin surface, improving suppleness and reducing transepidermal water loss.
โจ Niacinamide (Vitamin B3) ~2% (est. 1.9โ2.9%) Proven
One of the most extensively studied multitasking actives in modern dermatology. Third on the ingredient list behind rice extract and butylene glycol, WIMJ's analysis estimates the concentration at 1.9โ2.9% โ a level confirmed effective for barrier support and tone-evening without triggering the niacin flush sometimes seen at higher doses.
- Skin barrier: Stimulates ceramide synthesis in the stratum corneum, reducing transepidermal water loss (TEWL) and strengthening the protective skin barrier.
- Hyperpigmentation: Inhibits the transfer of melanosomes from melanocytes to keratinocytes, visibly reducing dark spots and post-acne marks over 8โ12 weeks of use.
- Anti-inflammatory: Reduces redness, blotchiness, and calms skin โ particularly beneficial for rosacea-prone, post-procedure, and acne-prone complexions.
- Sebum regulation: Clinical studies demonstrate niacinamide reduces sebaceous gland output, helping to control excess oiliness and shine.
๐ง Glycerin 4.1โ6.2% Proven
The gold-standard humectant in skincare science. Works by hydrogen-bonding with water molecules, drawing them from the dermis and environment into the epidermis. Partners synergistically with betaine and arginine in this formula for multi-layer overnight hydration.
- Humectant power: Significantly increases skin water content within 30 minutes of application, with sustained effect through the night.
- Aquaporin support: Supports aquaporin-3 channel production, helping skin better regulate its own internal hydration homeostasis.
- Barrier-compatible: At this concentration, glycerin softens and moisturizes without the tackiness that higher concentrations can produce.
๐ฟ Betaine 2.7โ4.0% Proven
A naturally derived osmolyte from sugar beet roots, betaine serves as a humectant, conditioning agent, and mild anti-irritant. It is a gentler and more biocompatible alternative to propylene glycol, valued for its osmoprotective properties in adverse environmental conditions.
- Humectant: Draws and retains moisture in the skin's upper layers, complementing the action of glycerin and arginine.
- Anti-irritant: Reduces skin irritation and can soothe mild inflammatory responses, supporting sensitive skin formulations.
- Osmoprotection: Protects skin cells from osmotic stress caused by dehydration, cold, or pollution exposure.
๐ป Helianthus Annuus (Sunflower) Seed Oil ~2โ4% Promising
A lightweight emollient oil rich in linoleic acid (approximately 68%) and Vitamin E. Helps condition the skin surface and contributes to the formula's smooth, non-greasy texture. Linoleic-rich oils are often recommended for acne-prone skin, as those with acne tend to have linoleic-deficient sebum.
- Linoleic acid (68%): Supports the skin lipid barrier and may benefit acne-prone skin by replenishing essential fatty acids depleted in acne-prone sebum.
- Emollient: Fills intercellular gaps in the stratum corneum, improving skin smoothness and reducing moisture loss and surface flakiness.
- Vitamin E: Provides antioxidant stabilization to other oils in the formula and contributes to skin-protective benefits.
๐ Allantoin <1% Proven
A time-tested soothing and skin-softening ingredient derived from comfrey root (or synthesized). Allantoin is one of the most universally well-tolerated skin-conditioning agents, commonly used in formulas targeting sensitive, irritated, or post-procedure skin.
- Keratolytic action: Gently softens and moisturizes the superficial skin layer, reducing roughness, flakiness, and improving overall skin texture.
- Wound healing: Accelerates skin cell regeneration and can calm irritated or compromised skin, supporting barrier recovery.
- Non-irritating: One of the gentlest functional ingredients available โ confirmed safe at concentrations up to 2% by multiple regulatory bodies.
๐ Arginine 0.15โ0.60% Promising
An essential amino acid that functions as both a humectant and a collagen synthesis stimulator in this formula. Part of the triple humectant complex alongside glycerin and betaine, arginine contributes to the formula's moisturizing depth and long-term skin health benefits.
- Humectant: As an amino acid, arginine draws and holds water in the skin, adding to the overall hydration matrix of the formula.
- Collagen stimulation: Arginine is a precursor to proline, an amino acid integral to collagen synthesis โ supporting long-term skin firmness and elasticity.
- Wound healing: Research suggests arginine supplementation may support collagen deposition and tissue repair in compromised skin.

๐ Where It Fits in Your Routine
Apply as the very last PM step on clean, toned, and treated skin. Use a pea-sized to fingertip amount, massage gently all over the face and neck, and rinse off the following morning with lukewarm water. Can also be used as a morning moisturizer โ simply apply as the final step before SPF.
๐ How to Use
Double Cleanse
Begin with an oil-based cleanser to remove SPF and makeup, followed by a foam or gel cleanser to clear the skin. Pat dry gently with a clean towel โ do not rub.
Apply Toner & Treatments
Layer your toner, essence, serum, and eye cream as usual. Allow each step to absorb before proceeding. This mask is designed to go on last to seal in all the goodness underneath.
Dispense a Pea-Sized Amount
Squeeze out a small, pea-sized to fingertip amount from the tube. Less is more โ using too thick a layer may create a slightly tacky sensation during sleep.
Massage Into Skin
Spread evenly across the face and neck using gentle upward circular motions. Massage lightly for better absorption. The gel-cream texture warms and melts into skin effortlessly.
Leave On Overnight (or Wash Off After 15 Minutes)
As an overnight mask: leave on until morning, then rinse with lukewarm water. As a wash-off treatment: leave on for 15 minutes then remove with toner or tepid water. As a daily cream: proceed with makeup or SPF.
๐ค Who Is It For?
โ Perfect for you if:
- Your skin feels dry, dehydrated, dull, or tight overnight
- You want gentle brightening without harsh active ingredients
- You prefer short, clean ingredient lists with minimal fillers
- You are new to K-beauty and want a reliable, proven sleeping mask
- You are pregnant or breastfeeding and need a safe nighttime moisturizer
- You want a multi-use product that works as a mask, cream, and treatment
- You have sensitive skin that reacts to fragrances and common allergens
โ Consider alternatives if:
- You have confirmed fungal acne (Malassezia folliculitis)
- You prefer ultra-lightweight, water-gel or serum-textured overnight masks
- You need strong anti-aging actives like retinoids, peptides, or high-dose Vitamin C
- You have very oily skin that finds cream-formula masks too heavy
- You are sensitive to olive oil derivatives (Cetearyl Olivate)
- You want dramatic, fast-visible brightening results within days
๐ฏ Skin Type Compatibility
The 68%+ rice extract plus triple humectant complex delivers the deep overnight nourishment dry skin needs. Wakes up feeling soft, plump, and replenished without tightness.
Provides ideal overnight maintenance hydration without over-moisturizing. The gel-cream texture balances nourishment and lightweight absorption for a glow-boosted morning complexion.
Works well on dry zones while remaining light enough on T-zone areas. Apply a thinner layer to oily areas and a slightly thicker one to dry cheeks for a tailored approach.
Niacinamide at 2% helps regulate sebum, but the emollient-rich formula may feel too rich for very oily skin types. Use a small pea-sized amount or try as a 15-minute wash-off mask instead.
Fragrance-free, EWG low-concern formula with soothing allantoin and arginine is generally well-tolerated. Patch test first if you have known olive oil or sunflower oil sensitivity.
The triple humectant complex (glycerin, betaine, arginine) directly targets transient dehydration, making this an ideal rescue mask after travel, flights, heated rooms, or heavy exfoliation nights.

โ Frequently Asked Questions
Yes, this mask is generally considered safe during pregnancy and breastfeeding. The formula contains no retinoids, no salicylic acid, no hydroquinone, no chemical sunscreen filters, and no harsh actives that are contraindicated during pregnancy. The key actives โ rice extract and niacinamide at 2% โ are both widely considered safe for use during pregnancy and lactation. As with any new skincare product, we recommend consulting your OB-GYN or midwife before adding it to your routine during pregnancy.
No โ this mask is NOT safe for fungal acne (Malassezia folliculitis). It contains several ingredients known to feed Malassezia yeast: Elaeis Guineensis (Palm) Oil, Elaeis Guineensis (Palm) Kernel Oil, Helianthus Annuus (Sunflower) Seed Oil, and fatty acid esters Cetearyl Olivate and Sorbitan Olivate. If you are managing fungal acne, look for FA-safe alternatives formulated without oils and fatty acid esters. The COSRX Snail Mucin 96% Power Essence is one FA-safe alternative from the same brand.
Yes, this mask is fully compatible with retinol, Vitamin C, AHAs (like glycolic and lactic acid), and BHAs (like salicylic acid). Because it contains no active acids or oxidation-sensitive actives itself, it can safely function as the final, sealing step after your active treatments. In fact, layering this mask over retinol or exfoliating acids is an excellent strategy โ the triple humectant complex and emollient rice proteins help buffer any dryness, peeling, or sensitivity caused by those actives, essentially acting as a barrier-repair sleep treatment.
This mask is best suited for normal, dry, dehydrated, and combination skin types. Those with dry or dehydrated skin will benefit most from the intensive overnight nourishment delivered by the 68%+ rice extract and triple humectant complex. Normal and combination skin types will enjoy the balanced gel-cream texture that hydrates without feeling heavy. Sensitive skin types generally tolerate it well given the fragrance-free, minimal formula. Oily skin types may find the formula slightly too emollient for nightly full-face use โ they may prefer using it as a 15-minute wash-off mask or applying only to dry areas.
You can expect to feel immediate hydration and softness from the very first night of use โ many users report plumper, softer skin by morning. Visible improvements in skin texture and smoothness typically appear within 1โ2 weeks of daily use. Brightening effects from the niacinamide and rice extract take longer โ most users notice a visible improvement in dullness and dark spots after 3โ4 weeks of consistent use. For the most significant tone-evening and barrier-strengthening benefits, plan for 6โ8 weeks of regular nightly application. Skincare results always vary by individual skin type, condition, and consistency of use.
This mask should always be the very last step of your PM (evening) skincare routine โ applied after your cleanser, toner, essence, serum, ampoule, and eye cream. As an occlusive-adjacent cream-mask, it works by sealing in all the active ingredients applied underneath and preventing transepidermal water loss while you sleep. It can also be used as a morning moisturizer: apply as the final step before SPF. As a wash-off mask, apply a generous amount after cleansing and leave on for 15 minutes before rinsing with lukewarm water.
The mask has a comedogenic rating of approximately 2 out of 5, which is generally considered low to non-comedogenic. While it contains palm oil (comedogenic rating 4) and palm kernel oil (comedogenic rating 4), these appear lower on the ingredient list at relatively small concentrations, and the overall formula has a predominantly non-comedogenic profile with dimethicone (rating 1), sunflower seed oil (rating 0โ2), and rice extract (rating 0). In community reviews, the vast majority of users โ including acne-prone users โ do not report pore-clogging. Patch testing is still recommended for very acne-prone skin before full-face use.
The recommended period after opening (PAO) is 12 months. The formula uses a combination of 1,2-Hexanediol and Ethylhexylglycerin as its preservative system, which is effective at maintaining microbial stability for this duration. A 60ml tube used nightly (pea-sized amount per application) will typically last 3โ4 months. If used more sparingly or alternated with other products, it can last up to 6 months or more. Always ensure the cap is tightly sealed after use and store away from heat and direct sunlight to preserve formula integrity.
Verdict: The COSRX Ultimate Nourishing Rice Overnight Spa Mask is a standout K-beauty sleeping mask that earns its cult status. With a genuinely impressive 68%+ rice extract concentration, a clinically effective 2% niacinamide, and a clean 19-ingredient formula that is fragrance-free, pregnancy-safe, and dermatologist-tested โ it delivers exceptional value for the price. The gel-cream texture is luxuriously soft without being greasy, and the 3-in-1 versatility (overnight mask, wash-off, or daily moisturizer) makes it a rare and practical multi-tasker. The main limitations are that it is not safe for fungal acne sufferers and may be too emollient for very oily skin types. Brightening results require patience โ this is a long-game product, not a quick fix. For dry, normal, dehydrated, or combination skin looking for a trustworthy, affordable, and evidence-backed overnight treatment: this belongs in your routine.

โ Frequently Asked Questions
Yes, this mask is generally considered safe during pregnancy and breastfeeding. The formula contains no retinoids, no salicylic acid, no hydroquinone, no chemical sunscreen filters, and no harsh actives that are contraindicated during pregnancy. The key actives โ rice extract and niacinamide at 2% โ are both widely considered safe for use during pregnancy and lactation. As with any new skincare product, we recommend consulting your OB-GYN or midwife before adding it to your routine during pregnancy.
No โ this mask is NOT safe for fungal acne (Malassezia folliculitis). It contains several ingredients known to feed Malassezia yeast: Elaeis Guineensis (Palm) Oil, Elaeis Guineensis (Palm) Kernel Oil, Helianthus Annuus (Sunflower) Seed Oil, and fatty acid esters Cetearyl Olivate and Sorbitan Olivate. If you are managing fungal acne, look for FA-safe alternatives formulated without oils and fatty acid esters. The COSRX Snail Mucin 96% Power Essence is one FA-safe alternative from the same brand.
Yes, this mask is fully compatible with retinol, Vitamin C, AHAs (like glycolic and lactic acid), and BHAs (like salicylic acid). Because it contains no active acids or oxidation-sensitive actives itself, it can safely function as the final, sealing step after your active treatments. In fact, layering this mask over retinol or exfoliating acids is an excellent strategy โ the triple humectant complex and emollient rice proteins help buffer any dryness, peeling, or sensitivity caused by those actives, essentially acting as a barrier-repair sleep treatment.
This mask is best suited for normal, dry, dehydrated, and combination skin types. Those with dry or dehydrated skin will benefit most from the intensive overnight nourishment delivered by the 68%+ rice extract and triple humectant complex. Normal and combination skin types will enjoy the balanced gel-cream texture that hydrates without feeling heavy. Sensitive skin types generally tolerate it well given the fragrance-free, minimal formula. Oily skin types may find the formula slightly too emollient for nightly full-face use โ they may prefer using it as a 15-minute wash-off mask or applying only to dry areas.
You can expect to feel immediate hydration and softness from the very first night of use โ many users report plumper, softer skin by morning. Visible improvements in skin texture and smoothness typically appear within 1โ2 weeks of daily use. Brightening effects from the niacinamide and rice extract take longer โ most users notice a visible improvement in dullness and dark spots after 3โ4 weeks of consistent use. For the most significant tone-evening and barrier-strengthening benefits, plan for 6โ8 weeks of regular nightly application. Skincare results always vary by individual skin type, condition, and consistency of use.
This mask should always be the very last step of your PM (evening) skincare routine โ applied after your cleanser, toner, essence, serum, ampoule, and eye cream. As an occlusive-adjacent cream-mask, it works by sealing in all the active ingredients applied underneath and preventing transepidermal water loss while you sleep. It can also be used as a morning moisturizer: apply as the final step before SPF. As a wash-off mask, apply a generous amount after cleansing and leave on for 15 minutes before rinsing with lukewarm water.
The mask has a comedogenic rating of approximately 2 out of 5, which is generally considered low to non-comedogenic. While it contains palm oil (comedogenic rating 4) and palm kernel oil (comedogenic rating 4), these appear lower on the ingredient list at relatively small concentrations, and the overall formula has a predominantly non-comedogenic profile with dimethicone (rating 1), sunflower seed oil (rating 0โ2), and rice extract (rating 0). In community reviews, the vast majority of users โ including acne-prone users โ do not report pore-clogging. Patch testing is still recommended for very acne-prone skin before full-face use.
The recommended period after opening (PAO) is 12 months. The formula uses a combination of 1,2-Hexanediol and Ethylhexylglycerin as its preservative system, which is effective at maintaining microbial stability for this duration. A 60ml tube used nightly (pea-sized amount per application) will typically last 3โ4 months. If used more sparingly or alternated with other products, it can last up to 6 months or more. Always ensure the cap is tightly sealed after use and store away from heat and direct sunlight to preserve formula integrity.
Verdict: The COSRX Ultimate Nourishing Rice Overnight Spa Mask is a standout K-beauty sleeping mask that earns its cult status. With a genuinely impressive 68%+ rice extract concentration, a clinically effective 2% niacinamide, and a clean 19-ingredient formula that is fragrance-free, pregnancy-safe, and dermatologist-tested โ it delivers exceptional value for the price. The gel-cream texture is luxuriously soft without being greasy, and the 3-in-1 versatility (overnight mask, wash-off, or daily moisturizer) makes it a rare and practical multi-tasker. The main limitations are that it is not safe for fungal acne sufferers and may be too emollient for very oily skin types. Brightening results require patience โ this is a long-game product, not a quick fix. For dry, normal, dehydrated, or combination skin looking for a trustworthy, affordable, and evidence-backed overnight treatment: this belongs in your routine.

๐ฌ Ingredient Breakdown
๐พ Oryza Sativa (Rice) Extract 68%+ Proven
The hero ingredient at an exceptional concentration, derived from Oryza sativa rice grains. Used for centuries across East and Southeast Asia for skin softening, brightening, and conditioning. At 68%+, it forms the primary aqueous base of this formula rather than a mere marketing addition.
- Antioxidant protection: Rich in flavonoids, ferulic acid, and Vitamin E that neutralize skin-damaging free radicals and help delay visible aging.
- Brightening mechanism: In-vitro studies show rice water inhibits tyrosinase enzyme activity, gradually reducing melanin production and fading dark spots over consistent use.
- Barrier support: A 2002 clinical study found rice baths improved skin barrier function and accelerated wound healing in patients with atopic dermatitis.
- Emollient action: Proteins in rice form a protective, moisture-trapping film on the skin surface, improving suppleness and reducing transepidermal water loss.
โจ Niacinamide (Vitamin B3) ~2% (est. 1.9โ2.9%) Proven
One of the most extensively studied multitasking actives in modern dermatology. Third on the ingredient list behind rice extract and butylene glycol, WIMJ's analysis estimates the concentration at 1.9โ2.9% โ a level confirmed effective for barrier support and tone-evening without triggering the niacin flush sometimes seen at higher doses.
- Skin barrier: Stimulates ceramide synthesis in the stratum corneum, reducing transepidermal water loss (TEWL) and strengthening the protective skin barrier.
- Hyperpigmentation: Inhibits the transfer of melanosomes from melanocytes to keratinocytes, visibly reducing dark spots and post-acne marks over 8โ12 weeks of use.
- Anti-inflammatory: Reduces redness, blotchiness, and calms skin โ particularly beneficial for rosacea-prone, post-procedure, and acne-prone complexions.
- Sebum regulation: Clinical studies demonstrate niacinamide reduces sebaceous gland output, helping to control excess oiliness and shine.
๐ง Glycerin 4.1โ6.2% Proven
The gold-standard humectant in skincare science. Works by hydrogen-bonding with water molecules, drawing them from the dermis and environment into the epidermis. Partners synergistically with betaine and arginine in this formula for multi-layer overnight hydration.
- Humectant power: Significantly increases skin water content within 30 minutes of application, with sustained effect through the night.
- Aquaporin support: Supports aquaporin-3 channel production, helping skin better regulate its own internal hydration homeostasis.
- Barrier-compatible: At this concentration, glycerin softens and moisturizes without the tackiness that higher concentrations can produce.
๐ฟ Betaine 2.7โ4.0% Proven
A naturally derived osmolyte from sugar beet roots, betaine serves as a humectant, conditioning agent, and mild anti-irritant. It is a gentler and more biocompatible alternative to propylene glycol, valued for its osmoprotective properties in adverse environmental conditions.
- Humectant: Draws and retains moisture in the skin's upper layers, complementing the action of glycerin and arginine.
- Anti-irritant: Reduces skin irritation and can soothe mild inflammatory responses, supporting sensitive skin formulations.
- Osmoprotection: Protects skin cells from osmotic stress caused by dehydration, cold, or pollution exposure.
๐ป Helianthus Annuus (Sunflower) Seed Oil ~2โ4% Promising
A lightweight emollient oil rich in linoleic acid (approximately 68%) and Vitamin E. Helps condition the skin surface and contributes to the formula's smooth, non-greasy texture. Linoleic-rich oils are often recommended for acne-prone skin, as those with acne tend to have linoleic-deficient sebum.
- Linoleic acid (68%): Supports the skin lipid barrier and may benefit acne-prone skin by replenishing essential fatty acids depleted in acne-prone sebum.
- Emollient: Fills intercellular gaps in the stratum corneum, improving skin smoothness and reducing moisture loss and surface flakiness.
- Vitamin E: Provides antioxidant stabilization to other oils in the formula and contributes to skin-protective benefits.
๐ Allantoin <1% Proven
A time-tested soothing and skin-softening ingredient derived from comfrey root (or synthesized). Allantoin is one of the most universally well-tolerated skin-conditioning agents, commonly used in formulas targeting sensitive, irritated, or post-procedure skin.
- Keratolytic action: Gently softens and moisturizes the superficial skin layer, reducing roughness, flakiness, and improving overall skin texture.
- Wound healing: Accelerates skin cell regeneration and can calm irritated or compromised skin, supporting barrier recovery.
- Non-irritating: One of the gentlest functional ingredients available โ confirmed safe at concentrations up to 2% by multiple regulatory bodies.
๐ Arginine 0.15โ0.60% Promising
An essential amino acid that functions as both a humectant and a collagen synthesis stimulator in this formula. Part of the triple humectant complex alongside glycerin and betaine, arginine contributes to the formula's moisturizing depth and long-term skin health benefits.
- Humectant: As an amino acid, arginine draws and holds water in the skin, adding to the overall hydration matrix of the formula.
- Collagen stimulation: Arginine is a precursor to proline, an amino acid integral to collagen synthesis โ supporting long-term skin firmness and elasticity.
- Wound healing: Research suggests arginine supplementation may support collagen deposition and tissue repair in compromised skin.

๐ Where It Fits in Your Routine
Apply as the very last PM step on clean, toned, and treated skin. Use a pea-sized to fingertip amount, massage gently all over the face and neck, and rinse off the following morning with lukewarm water. Can also be used as a morning moisturizer โ simply apply as the final step before SPF.
๐ How to Use
Double Cleanse
Begin with an oil-based cleanser to remove SPF and makeup, followed by a foam or gel cleanser to clear the skin. Pat dry gently with a clean towel โ do not rub.
Apply Toner & Treatments
Layer your toner, essence, serum, and eye cream as usual. Allow each step to absorb before proceeding. This mask is designed to go on last to seal in all the goodness underneath.
Dispense a Pea-Sized Amount
Squeeze out a small, pea-sized to fingertip amount from the tube. Less is more โ using too thick a layer may create a slightly tacky sensation during sleep.
Massage Into Skin
Spread evenly across the face and neck using gentle upward circular motions. Massage lightly for better absorption. The gel-cream texture warms and melts into skin effortlessly.
Leave On Overnight (or Wash Off After 15 Minutes)
As an overnight mask: leave on until morning, then rinse with lukewarm water. As a wash-off treatment: leave on for 15 minutes then remove with toner or tepid water. As a daily cream: proceed with makeup or SPF.
๐ค Who Is It For?
โ Perfect for you if:
- Your skin feels dry, dehydrated, dull, or tight overnight
- You want gentle brightening without harsh active ingredients
- You prefer short, clean ingredient lists with minimal fillers
- You are new to K-beauty and want a reliable, proven sleeping mask
- You are pregnant or breastfeeding and need a safe nighttime moisturizer
- You want a multi-use product that works as a mask, cream, and treatment
- You have sensitive skin that reacts to fragrances and common allergens
โ Consider alternatives if:
- You have confirmed fungal acne (Malassezia folliculitis)
- You prefer ultra-lightweight, water-gel or serum-textured overnight masks
- You need strong anti-aging actives like retinoids, peptides, or high-dose Vitamin C
- You have very oily skin that finds cream-formula masks too heavy
- You are sensitive to olive oil derivatives (Cetearyl Olivate)
- You want dramatic, fast-visible brightening results within days
๐ฏ Skin Type Compatibility
The 68%+ rice extract plus triple humectant complex delivers the deep overnight nourishment dry skin needs. Wakes up feeling soft, plump, and replenished without tightness.
Provides ideal overnight maintenance hydration without over-moisturizing. The gel-cream texture balances nourishment and lightweight absorption for a glow-boosted morning complexion.
Works well on dry zones while remaining light enough on T-zone areas. Apply a thinner layer to oily areas and a slightly thicker one to dry cheeks for a tailored approach.
Niacinamide at 2% helps regulate sebum, but the emollient-rich formula may feel too rich for very oily skin types. Use a small pea-sized amount or try as a 15-minute wash-off mask instead.
Fragrance-free, EWG low-concern formula with soothing allantoin and arginine is generally well-tolerated. Patch test first if you have known olive oil or sunflower oil sensitivity.
The triple humectant complex (glycerin, betaine, arginine) directly targets transient dehydration, making this an ideal rescue mask after travel, flights, heated rooms, or heavy exfoliation nights.
