🔬 Ingredient Breakdown
💧 Multi-Molecular Hyaluronic Acid 2% Proven
A powerful humectant that occurs naturally in skin and can hold up to 1000x its weight in water. This formula uses multiple molecular weights to hydrate different skin layers.
- High Molecular Weight: Forms a protective film on skin surface, preventing moisture loss
- Low Molecular Weight: Penetrates deeper into skin for lasting hydration from within
- Clinical Benefit: Improves skin elasticity, plumpness, and reduces appearance of fine lines
🧬 Matrixyl 3000 (Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7) 2% Proven
A patented peptide complex combining two peptides that work synergistically to stimulate collagen production and reduce inflammation for visible anti-aging benefits.
- Palmitoyl Tripeptide-1: Signals skin to produce new collagen, improving firmness and reducing wrinkles
- Palmitoyl Tetrapeptide-7: Reduces inflammation by limiting IL-6 production, protecting collagen from breakdown
- Clinical Studies: Shown to reduce wrinkle depth by up to 45% in clinical trials
🌿 Glycerin Proven
A powerful humectant that draws moisture into skin. Studies show glycerin may be more effective than hyaluronic acid at improving skin hydration.
- Function: Attracts water molecules to keep skin hydrated and supple
- Skin Barrier: Helps strengthen the skin barrier function
- Safety: Extensively studied, non-irritating, suitable for all skin types
🥬 Leuconostoc/Radish Root Ferment Filtrate Promising
A natural preservative derived from fermenting radish roots with lactobacillus bacteria. Provides antimicrobial protection without synthetic preservatives.
- Function: Natural alternative to synthetic preservatives
- Benefit: Antimicrobial properties help extend product shelf life
- Source: Same fermentation process used to make kimchi and sourdough
14 ingredients
Water (Aqua/Eau), Propanediol, Sodium Hyaluronate, Glycerin, Butylene Glycol, Phenoxyethanol, Ammonium Acryloyldimethyltaurate/VP Copolymer, Leuconostoc/Radish Root Ferment Filtrate, Hyaluronic Acid, Carbomer, Sodium Lactate, Polysorbate 20, Palmitoyl Tetrapeptide-7, Palmitoyl Tripeptide-1
🔄 Where It Fits in Your Routine
Apply immediately after cleansing on damp skin to maximize hydration. Follow with other serums and moisturizer to lock in benefits.
📝 How to Use
Cleanse & Leave Skin Damp
After cleansing, don't completely dry your face. Hyaluronic acid works best when applied to damp skin as it draws moisture in.
Apply Pea-Sized Amount
Dispense a pea-sized amount onto fingertips. A little goes a long way with this concentrated formula.
Gently Pat Into Skin
Pat gently onto face and neck. Avoid rubbing to prevent irritation and allow the serum to absorb properly.
Follow With Moisturizer
Always seal with a moisturizer to lock in the hydration. This prevents the HA from drawing moisture out of your skin in dry environments.

- You have dehydrated or dry skin
- You want to reduce the appearance of fine lines
- You need a lightweight, non-sticky hydrating serum
- You're pregnant or breastfeeding
- You want an affordable entry into skincare actives
- You prefer fragrance-free products
- You need a serum that layers well under makeup
❌ Consider alternatives if:

🎯 Skin Type Compatibility
Lightweight, water-based formula absorbs instantly without adding shine or greasiness. Won't clog pores.

Balances well across different face zones. Hydrates dry areas without overwhelming oily T-zone.
Fragrance-free, gentle formula with minimal potential irritants. Most sensitive skin types tolerate it well.
Non-comedogenic and oil-free. However, not suitable for fungal acne due to polysorbate and peptide content.
Matrixyl 3000 peptide specifically targets fine lines and supports collagen production for anti-aging benefits.

❓ Frequently Asked Questions
Yes, this serum is considered safe during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. Hyaluronic acid and peptides are both pregnancy-safe ingredients. The brand has confirmed this product is safe for use during pregnancy.
No, this serum is NOT fungal acne safe. It contains Polysorbate 20 and palmitoyl peptides (Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7) which have a palmitic acid base that can feed Malassezia yeast. If you have fungal acne, consider The Ordinary Hyaluronic Acid 2% + B5 as an alternative.
Yes! Hyaluronic acid is compatible with virtually all active ingredients including retinol, vitamin C, niacinamide, AHAs, and BHAs. In fact, using HA with these actives can help buffer potential irritation and keep skin hydrated. Apply the HA serum first to damp skin, then layer your other treatments on top.
This serum works well for all skin types including oily, dry, combination, sensitive, and mature skin. It's particularly excellent for oily and combination skin due to its lightweight, non-greasy texture. Dry skin types may need to pair it with a heavier moisturizer for optimal results.
You'll notice instant hydration immediately after application. Improved skin texture typically appears within 1-2 weeks of consistent use. The anti-aging benefits from the Matrixyl 3000 peptide (reduced fine lines, improved firmness) become visible around 4-6 weeks with twice-daily use.
Apply this serum immediately after cleansing (and toning, if you use one) while your skin is still damp. The damp skin helps the hyaluronic acid draw in maximum moisture. Follow with any treatment serums, then moisturizer to seal in hydration, and sunscreen in the morning.
No, this serum has a very low comedogenic rating of 1/5. It's oil-free, silicone-free, and contains no ingredients known to clog pores. The lightweight, water-based formula absorbs quickly and is suitable for acne-prone skin (though not for fungal acne).
The serum has a PAO (Period After Opening) of 12 months. Store it in a cool, dry place away from direct sunlight. If you notice any changes in color, texture, or smell, discontinue use. The opaque packaging helps protect the formula from light degradation.
Verdict: The Inkey List Hyaluronic Acid Serum is an exceptional value in the hydrating serum category. At under $10, it delivers clinical-grade hydration with 2% multi-molecular Hyaluronic Acid plus the bonus of Matrixyl 3000 peptide for anti-aging benefits—a combination rarely found at this price point. The non-tacky texture sets it apart from competitors like The Ordinary, making it a joy to use daily. While it's not suitable for those with fungal acne, it's an excellent choice for everyone else looking to boost hydration, improve skin texture, and reduce fine lines without breaking the bank. A must-have for beginners and skincare enthusiasts alike.
