Ingredient review
C12-13 Alkyl Glyceryl Hydrolyzed Hyaluronate
INCI: C12-13 ALKYL GLYCERYL HYDROLYZED HYALURONATE
A next-gen hyaluronic acid that sticks to skin longer for lasting hydration without greasiness.
In plain English
This is a souped-up version of hyaluronic acid, a natural moisture magnet found in your skin. Scientists attached a fatty chain (C12-13 alkyl) and a glycerin-like piece to the hyaluronic acid molecule. This helps it cling to your skin's surface instead of rinsing off easily, so it keeps pulling in water for hours. Think of it as hyaluronic acid with better grip and staying power.

Quick decision guide
Easy yes for most routines
C12-13 Alkyl Glyceryl Hydrolyzed Hyaluronate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging C12-13 Alkyl Glyceryl Hydrolyzed Hyaluronate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic derivative of hydrolyzed hyaluronic acid, modified with a C12-13 alkyl chain and a glyceryl group to enhance skin affinity and film-forming ability.
How it works
The alkyl chain anchors the molecule to the skin's lipid barrier, while the glyceryl group adds extra water-binding capacity. This dual action creates a thin, flexible film that continuously attracts moisture from the air and deeper skin layers, reducing water loss (transepidermal water loss, or TEWL).
Pros
Stays put longer
The alkyl modification helps the ingredient adhere to skin, so it doesn't wash off or rub away as quickly as standard hyaluronic acid.
Dual-action moisture
Both humectant (pulls water in) and film-forming (locks it in) properties give you more bang for your buck in a single ingredient.
Cons and cautions
Premium price
Because it's a specialized derivative, products containing it tend to cost more than those with plain hyaluronic acid.
Potential tackiness
At higher concentrations or in humid weather, the film it forms can feel slightly sticky or tacky on the skin.
Best for
- Anyone with dry or dehydrated skin
- People who want a lightweight but long-lasting moisturizer
Use caution if
- Those with very oily skin who prefer a matte finish (may feel too rich)
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Low irritation and comedogenic risk. No significant safety concerns reported in cosmetic use.
Research notes
Limited but promising evidence from ingredient suppliers and formulation studies shows improved skin retention and hydration compared to unmodified hyaluronic acid. More independent clinical research is needed.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Serums, Moisturizers, Eye creams, Sheet masks
- Environmental note
- Semi-synthetic; production involves chemical modification of naturally derived hyaluronic acid. Biodegradability is not well documented.
Good to know
- This ingredient is often found in 'next-gen' or 'advanced' hyaluronic acid serums.
- It is compatible with most other skincare ingredients, including vitamin C and retinol.
