Honest Hyaluronic Acid Serum
A minimalist, dermatologist-developed hydrating serum that combines pure hyaluronic acid with vitamin B5 to deeply hydrate, plump, and smooth skin. This oil-free formula is an excellent affordable alternative to premium serums like SkinCeuticals Hydrating B5 Gel.
✨ Texture & Feel
Intense Hydration
Hyaluronic acid holds up to 1000x its weight in water, drawing moisture into all skin layers for plump, supple skin.
Ultra-Pure Formula
Only 4 carefully selected ingredients. No fillers, no fragrances, no unnecessary additives that could irritate skin.
Barrier Repair
Vitamin B5 (Calcium Pantothenate) promotes the skin's natural repair process and helps heal damaged tissue.
Anti-Aging Benefits
Reduces appearance of fine lines and wrinkles by plumping dehydrated skin from within.
🛡️ Safety & Compatibility
Contains only hyaluronic acid, vitamin B5, and a gentle preservative. All ingredients are considered safe for use during pregnancy and nursing.
Free from fatty acids, oils, esters, and ferments that feed Malassezia yeast. Hyaluronic acid and vitamin B5 are humectants that do not promote fungal growth.
Oil-free, water-based formula with no pore-clogging ingredients. Ideal for acne-prone skin.
No fragrances, dyes, alcohols, or parabens. Minimal ingredient list reduces risk of irritation.
Safe to use with retinol, vitamin C, AHAs, BHAs, and niacinamide. Apply after water-based actives, before oils and creams.
Sourced through bio-fermentation rather than animal-derived sources. Cruelty-free formulation.
🔬 Ingredient Breakdown
💧 Sodium Hyaluronate (Hyaluronic Acid) Proven
The star ingredient of this serum. Sodium hyaluronate is the salt form of hyaluronic acid, naturally found in skin. It acts as a powerful humectant, attracting and binding moisture to keep skin hydrated, plump, and youthful-looking.
- Mechanism: Can hold up to 1000x its weight in water, drawing moisture from the environment into the skin
- Benefits: Reduces appearance of fine lines, improves skin texture, enhances elasticity
- Research: Extensively studied ingredient with decades of clinical evidence supporting hydration benefits
🧬 Calcium Pantothenate (Vitamin B5) Proven
Also known as provitamin B5 or pantothenic acid. This essential nutrient supports the skin barrier's natural repair process and provides additional humectant benefits alongside hyaluronic acid.
- Mechanism: Penetrates skin and converts to pantothenic acid, supporting tissue regeneration
- Benefits: Promotes wound healing, reduces inflammation, enhances skin softness
- Synergy: Works synergistically with hyaluronic acid to maximize moisture retention
🛡️ Phenoxyethanol <1% Preservative
A widely-used, gentle preservative that prevents microbial growth and extends shelf life. Considered safe for cosmetic use at concentrations up to 1%.
- Safety: Approved by FDA, EU, and cosmetic regulatory bodies worldwide
- Function: Broad-spectrum antimicrobial activity against bacteria and fungi
- Advantage: Paraben-free alternative that maintains product stability
4 ingredients
Water, Calcium Pantothenate (Vitamin B5), Sodium Hyaluronate (Hyaluronic Acid), Phenoxyethanol
🔄 Where It Fits in Your Routine
Apply to damp skin after water-based actives. In the AM, use after vitamin C serum. In the PM, apply after retinol. Always follow with moisturizer.
📝 How to Use
Cleanse & Prep
Start with clean, slightly damp skin. The water helps hyaluronic acid draw moisture into the skin rather than pulling it from deeper layers.
Apply 2-3 Drops
Using fingertips, apply 2-3 drops to the entire face, neck, and chest. Avoid the eye area. A little goes a long way.
Gently Pat In
Use gentle patting motions to help the serum absorb. The lightweight formula should absorb within 1-2 minutes without stickiness.
Seal with Moisturizer
Immediately follow with your favorite moisturizer to lock in hydration. This prevents the HA from drawing moisture out of your skin in dry climates.
👤 Who Is It For?
✅ Perfect for you if:
- You want a simple, effective hydrating serum without fillers
- You have dehydrated or dull-looking skin
- You're looking for a SkinCeuticals Hydrating B5 dupe
- You have acne-prone or fungal acne-prone skin
- You're pregnant or breastfeeding and need safe hydration
- You want to boost the effectiveness of your moisturizer
- You're recovering from treatments (peels, microneedling, laser)
- You prefer minimalist, clean formulas
❌ Consider alternatives if:
- You need deep moisturization and occlusion (this is a humectant only)
- You live in an extremely dry climate without layering a moisturizer
- You want multi-molecular weight HA for deeper penetration
- You prefer a thicker, more luxurious texture
- You want additional active ingredients like niacinamide or peptides
🎯 Skin Type Compatibility
Lightweight, oil-free formula absorbs quickly without adding shine or greasiness. Provides hydration without clogging pores.
Excellent hydration boost, but must be layered with a rich moisturizer on top. HA alone won't provide enough occlusion for very dry skin.
Perfect for balancing hydration across different face zones without adding oil to T-zone or leaving dry areas parched.
Fragrance-free, minimal ingredient formula with only 4 ingredients. Very low risk of irritation. Vitamin B5 provides soothing benefits.
Non-comedogenic (0/5), oil-free, and fungal acne safe. Provides hydration without triggering breakouts. Ideal for acne-prone skin.

❓ Frequently Asked Questions
Yes, this serum is completely safe during pregnancy and breastfeeding. It contains only 4 ingredients: water, calcium pantothenate (vitamin B5), sodium hyaluronate (hyaluronic acid), and phenoxyethanol. None of these ingredients are on the list of ingredients to avoid during pregnancy (like retinoids, salicylic acid, hydroquinone, etc.). Hyaluronic acid is naturally produced by our bodies and is considered safe for topical use during pregnancy.
Yes, this serum is 100% fungal acne safe. The formula contains no fatty acids, oils, esters, polysorbates, or ferments that feed Malassezia yeast. Hyaluronic acid and vitamin B5 are both humectants that hydrate without providing nutrients for fungal growth. This makes it an excellent choice for those dealing with pityrosporum folliculitis.
Absolutely! Hyaluronic acid is compatible with virtually all actives including retinol, vitamin C, AHAs (glycolic, lactic acid), BHAs (salicylic acid), and niacinamide. In fact, it can help buffer potential irritation from strong actives by providing hydration. Apply water-based actives first, then the HA serum, then follow with moisturizer. In the AM, use after vitamin C serum. In the PM, apply after retinol.
This serum is excellent for all skin types! It's particularly well-suited for oily, combination, acne-prone, and sensitive skin due to its oil-free, fragrance-free, minimal formula. Dry skin types will benefit greatly but should always layer a moisturizer on top, as HA is a humectant (draws water) rather than an occlusive (seals moisture in).
You'll feel immediate hydration and a plumping effect right after application. Visible improvement in skin texture typically occurs within 1-2 weeks of consistent use. Reduction in fine lines and overall skin health improvements are usually noticeable after 4-8 weeks of daily use. Best results come from using it twice daily (AM and PM) consistently.
Apply this serum after cleansing, toning, and any water-based actives (like vitamin C or retinol), but before heavier products like oils and moisturizers. The general rule is thin to thick consistency. Pro tip: Apply to slightly damp skin to help HA draw moisture in, then immediately seal with moisturizer.
No, this serum has a comedogenic rating of 0/5. It is completely non-comedogenic and will not clog pores. The oil-free, water-based formula with just 4 ingredients is specifically designed to be safe for acne-prone skin. It's often recommended for those with acne because it provides hydration without contributing to breakouts.
The serum has a shelf life of 12 months after opening (PAO 12M). Store it in a cool, dry place away from direct sunlight to maintain optimal potency. While refrigeration isn't necessary, it can help extend freshness. The 2oz bottle typically lasts 3-4 months with twice-daily use (2-3 drops per application).
Verdict: Dr. Brenner Honest Hyaluronic Acid Serum is an excellent choice for anyone seeking effective, no-frills hydration at a fraction of luxury prices. With its ultra-minimal 4-ingredient formula identical to SkinCeuticals Hydrating B5 Gel ($95), this dermatologist-developed serum delivers the same hydrating benefits for under $17. It's pregnancy-safe, fungal acne-safe, and works beautifully for all skin types. While some users prefer the multi-molecular weight approach of The Ordinary or additional soothing ingredients, this serum's simplicity is its strength—perfect for sensitive, reactive, or minimalist skincare routines. Best used on damp skin with a moisturizer layered on top.
