Ingredient review
Dihydrocholesteryl Butyrate
INCI: Dihydrocholesteryl Butyrate
A gentle, cholesterol-based emollient that helps reinforce the skin barrier and lock in moisture without clogging pores.
In plain English
Dihydrocholesteryl Butyrate is a semi-synthetic ingredient made from cholesterol, a natural fat found in your skin. In skincare, it acts like a building block for your skin barrier, helping to fill in gaps between skin cells so moisture stays in and irritants stay out. Think of it as a repair mortar for your skin's brick wall.

Quick decision guide
Useful, but context matters
Dihydrocholesteryl Butyrate 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 Dihydrocholesteryl Butyrate.
- 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
Dihydrocholesteryl Butyrate is an ester formed by combining dihydrocholesterol (a hydrogenated form of cholesterol) with butyric acid. It is a waxy, lipid-like substance designed to mimic the skin's natural fats.
How it works
When applied topically, it integrates into the lipid matrix of the stratum corneum (the outermost skin layer). It helps restore the barrier function by replenishing lost cholesterol, reducing transepidermal water loss (TEWL), and improving skin softness and smoothness.
Pros
Barrier support
Helps repair and maintain the skin's natural barrier, which is essential for keeping moisture in and irritants out.
Lightweight feel
Unlike some heavy oils, it absorbs quickly without leaving a greasy residue, making it suitable for daytime use.
Cons and cautions
Limited independent research
Most evidence comes from studies on cholesterol itself; specific data on this ester is sparse, so its unique benefits are less documented.
Potential for variability
Effectiveness can vary depending on the formulation and the rest of the ingredient blend, so results may not be consistent across products.
Best for
- People with dry or dehydrated skin
- Those with a compromised skin barrier (e.g., from over-exfoliation or harsh weather)
Use caution if
- Individuals with a known allergy to cholesterol derivatives (rare)
Usage tips
Safety summary
Generally recognized as safe for topical use at typical concentrations. Low irritation and comedogenic risk. Patch testing is recommended for sensitive individuals, though adverse reactions are rare.
Research notes
Evidence is primarily extrapolated from studies on cholesterol and other skin-identical lipids. Direct studies on Dihydrocholesteryl Butyrate are limited, but its structural similarity to natural cholesterol supports its barrier-repair function.
Common label clues
- Typical concentration
- 0.5% to 3%
- 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
- Moisturizers, Anti-aging creams, Barrier repair products
- Environmental note
- Semi-synthetic production reduces reliance on animal-derived cholesterol, but the environmental impact of synthesis is not well-documented.
Good to know
- It is often paired with ceramides and fatty acids in barrier-repair formulas.
- The butyrate component may have mild anti-inflammatory properties, though more research is needed.
