πŸ”¬ Ingredient Breakdown

🍢 Galactomyces Ferment Filtrate 60% Proven

A yeast ferment (similar to SK-II's Pitera) that brightens skin, minimizes pores, reduces sebum production, and improves overall skin texture and radiance.

  • Research: Studies show decreased pore size, reduced blackheads, and improved brightness
  • Mechanism: Activates AHR and NRF2 pathways for antioxidant protection and barrier support
⚠️
Not suitable for those with fungal acne (malassezia folliculitis)

πŸ’Š Niacinamide (Vitamin B3) 2% Proven

A well-researched multitasker that regulates melanin production, strengthens the skin barrier, reduces inflammation, and minimizes the appearance of pores.

  • Efficacy: 2% effective for barrier support and evening skin tone
  • Benefits: Anti-inflammatory, anti-aging, sebum-regulating, brightening
βœ…
Gentle concentration suitable for sensitive skin; pairs well with most actives

🎯 Tranexamic Acid Proven

A powerful brightening agent that inhibits plasmin activity to reduce melanin synthesis. Effective for post-inflammatory hyperpigmentation and melasma.

  • Mechanism: Constricts blood vessels and prevents excess pigmentation
  • Synergy: Works synergistically with niacinamide for enhanced brightening

🐌 Snail Secretion Filtrate Promising

Italian-sourced snail mucin rich in glycoproteins, hyaluronic acid, and peptides. Supports skin regeneration and helps smooth textural irregularities.

  • Benefits: Wound healing, hydration, anti-inflammatory, texture smoothing
  • Ethics: Obtained amicably without harming snails

🧬 Melatrepeinβ„’ 5000 Proprietary

A patented peptide complex that works like a "clean-up crew" to degrade existing melanosomes and prevent new ones from forming.

  • Action: Targets pigment-containing cells for reduction in hyperpigmentation
  • Result: Brighter, more even-toned complexion with continued use

Apply after cleansing and toning, before heavier serums and moisturizer. Can be used AM and PM. Always follow with SPF during the day.

πŸ“ How to Use

1

Start with Clean Skin

After cleansing (and toning if desired), ensure skin is clean and slightly damp for better absorption.

2

Dispense 3-6 Drops

Start with 3 drops for beginners. As skin adjusts and absorbs more easily, increase to 6 drops or half a dropper.

3

Press Into Skin

Gently press and pat the product into skin until fully absorbed. The oil-like texture will absorb quickly.

4

Continue Routine + SPF

Follow with remaining skincare. Apply SPF dailyβ€”while Niacid doesn't cause sun sensitivity, UV exposure impedes healing.

❓ Frequently Asked Questions

Use with caution. While topical niacinamide and tranexamic acid are generally considered safe during pregnancy (Category B), Niacid contains snail mucin and galactomyces ferment which have limited safety data for pregnant/nursing mothers. Consult your healthcare provider before use.

No, Niacid is NOT safe for fungal acne. It contains 60% Galactomyces Ferment Filtrate, a yeast-derived ingredient that can feed Malassezia and worsen fungal acne. If you have malassezia folliculitis, consider alternatives like Good Molecules Discoloration Correcting Serum or The Ordinary Niacinamide 10% + Zinc 1%.

Yes! Niacid pairs well with most actives. Niacinamide and vitamin C can be used together despite old myths. For retinol/AHA/BHA, apply Niacid first, wait a few minutes, then apply the other active. Alternatively, use them at different times of day (Niacid AM, actives PM or vice versa).

Niacid is formulated for all skin types including sensitive skin. It's especially excellent for oily, combination, and acne-prone (non-fungal) skin. The oil-free, fragrance-free formula won't clog pores or cause irritation. Dry skin types can use it but should follow with a richer moisturizer.

Many users notice an immediate brightness boost overnight. Fading of blemishes and healing of indentations typically becomes prominent during days 3-7 and continues improving cumulatively. Significant results for hyperpigmentation usually appear within 2-4 weeks with consistent use. Full transformation may take 2+ months.

Apply Niacid after cleansing and toning, as step 3 in your routine. Dispense 3-6 drops onto palms and press into skin. Follow with serums, moisturizer, and sunscreen (AM). Niacid can be used both morning and night. Always use SPF during the day to protect healing skin.

No, Niacid has a low comedogenic rating of 1/5. The oil-free formula is designed to absorb fully without clogging pores. It's safe for acne-prone skin (non-fungal type). The transdermal technology actually helps the formula penetrate rather than sit on top of skin.

Niacid has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight to maintain efficacy. The glass dropper bottle helps protect the formula from degradation. If you notice any changes in color, texture, or smell, discontinue use.

Verdict: Slurp Niacid is an innovative K-beauty serum that delivers on its promise to fade acne scars and brighten skin. The unique transdermal technology and powerhouse combination of 60% Galactomyces, niacinamide, tranexamic acid, and snail mucin make it a standout product for those dealing with PIE/PIH. While the premium price and unsuitability for fungal acne are drawbacks, the fragrance-free, oil-free formula with visible results makes it worth the investment for the right skin concerns.

Apply after cleansing and toning, before heavier serums and moisturizer. Can be used AM and PM. Always follow with SPF during the day.

πŸ“ How to Use

1

Start with Clean Skin

After cleansing (and toning if desired), ensure skin is clean and slightly damp for better absorption.

2

Dispense 3-6 Drops

Start with 3 drops for beginners. As skin adjusts and absorbs more easily, increase to 6 drops or half a dropper.

3

Press Into Skin

Gently press and pat the product into skin until fully absorbed. The oil-like texture will absorb quickly.

4

Continue Routine + SPF

Follow with remaining skincare. Apply SPF dailyβ€”while Niacid doesn't cause sun sensitivity, UV exposure impedes healing.

❓ Frequently Asked Questions

Use with caution. While topical niacinamide and tranexamic acid are generally considered safe during pregnancy (Category B), Niacid contains snail mucin and galactomyces ferment which have limited safety data for pregnant/nursing mothers. Consult your healthcare provider before use.

No, Niacid is NOT safe for fungal acne. It contains 60% Galactomyces Ferment Filtrate, a yeast-derived ingredient that can feed Malassezia and worsen fungal acne. If you have malassezia folliculitis, consider alternatives like Good Molecules Discoloration Correcting Serum or The Ordinary Niacinamide 10% + Zinc 1%.

Yes! Niacid pairs well with most actives. Niacinamide and vitamin C can be used together despite old myths. For retinol/AHA/BHA, apply Niacid first, wait a few minutes, then apply the other active. Alternatively, use them at different times of day (Niacid AM, actives PM or vice versa).

Niacid is formulated for all skin types including sensitive skin. It's especially excellent for oily, combination, and acne-prone (non-fungal) skin. The oil-free, fragrance-free formula won't clog pores or cause irritation. Dry skin types can use it but should follow with a richer moisturizer.

Many users notice an immediate brightness boost overnight. Fading of blemishes and healing of indentations typically becomes prominent during days 3-7 and continues improving cumulatively. Significant results for hyperpigmentation usually appear within 2-4 weeks with consistent use. Full transformation may take 2+ months.

Apply Niacid after cleansing and toning, as step 3 in your routine. Dispense 3-6 drops onto palms and press into skin. Follow with serums, moisturizer, and sunscreen (AM). Niacid can be used both morning and night. Always use SPF during the day to protect healing skin.

No, Niacid has a low comedogenic rating of 1/5. The oil-free formula is designed to absorb fully without clogging pores. It's safe for acne-prone skin (non-fungal type). The transdermal technology actually helps the formula penetrate rather than sit on top of skin.

Niacid has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight to maintain efficacy. The glass dropper bottle helps protect the formula from degradation. If you notice any changes in color, texture, or smell, discontinue use.

Verdict: Slurp Niacid is an innovative K-beauty serum that delivers on its promise to fade acne scars and brighten skin. The unique transdermal technology and powerhouse combination of 60% Galactomyces, niacinamide, tranexamic acid, and snail mucin make it a standout product for those dealing with PIE/PIH. While the premium price and unsuitability for fungal acne are drawbacks, the fragrance-free, oil-free formula with visible results makes it worth the investment for the right skin concerns.
