Ingredient review
Resveratryl Tricaprylate
INCI: Resveratryl Tricaprylate
A stabilized, oil-soluble form of resveratrol that offers antioxidant protection and anti-aging benefits with better stability and skin penetration than plain resveratrol.
In plain English
Resveratryl Tricaprylate is a modified version of resveratrol, the antioxidant found in red wine and grapes. By attaching caprylic acid (a fatty acid from coconut oil), it becomes oil-soluble and more stable, so it can penetrate deeper into skin and last longer on the shelf. It helps protect skin from environmental damage and may support collagen health.

Quick decision guide
Useful, but context matters
Resveratryl Tricaprylate 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 Resveratryl Tricaprylate.
- 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
Resveratryl Tricaprylate is a semi-synthetic ester created by combining resveratrol (a natural polyphenol antioxidant) with caprylic acid (a medium-chain fatty acid). This chemical modification makes the ingredient oil-soluble, more stable against light and air, and better able to penetrate the skin's lipid barrier compared to plain resveratrol.
How it works
Once applied, Resveratryl Tricaprylate is thought to be broken down by skin enzymes into resveratrol and caprylic acid. The released resveratrol then acts as an antioxidant, neutralizing free radicals that cause premature aging. The caprylic acid portion may also help condition the skin. Its oil-solubility allows it to integrate into moisturizing formulas and deliver resveratrol deeper into the epidermis.
Pros
Enhanced stability
Unlike plain resveratrol, which degrades quickly in light and air, Resveratryl Tricaprylate is much more stable, giving products a longer shelf life.
Better skin penetration
Its oil-soluble nature allows it to absorb more easily into the skin's lipid barrier, potentially delivering antioxidant benefits deeper than water-soluble resveratrol.
Cons and cautions
Limited human research
Most evidence comes from lab studies or is inferred from resveratrol research. Few large-scale human trials specifically test Resveratryl Tricaprylate.
Potentially lower potency
Because the molecule is larger and includes caprylic acid, the actual resveratrol content by weight is lower, so you may need a higher concentration for the same antioxidant effect.
Best for
- People looking for a stable, oil-soluble antioxidant for anti-aging routines
- Those with dry or normal skin who prefer oil-based or creamy formulas
- Anyone wanting to add resveratrol benefits without the stability issues of plain resveratrol
Use caution if
- Individuals with known allergies to resveratrol or caprylic acid (rare)
- Those who prefer water-based serums and avoid all oil-soluble ingredients
Usage tips
Safety summary
Resveratryl Tricaprylate is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. As a modified ester, it is less likely to cause sensitivity than some other antioxidants. Patch testing is recommended for those with very sensitive skin.
Research notes
Research on Resveratryl Tricaprylate is still emerging. Most evidence is based on in vitro (lab) studies showing antioxidant activity and improved stability. Human studies are limited but suggest good tolerability and potential anti-aging benefits. More clinical trials are needed to confirm efficacy compared to plain resveratrol.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Anti-aging serums, Moisturizers, Eye creams, Sunscreen formulations
- Environmental note
- Caprylic acid is typically derived from coconut or palm oil. Look for sustainably sourced palm oil if that is a concern.
Good to know
- Resveratryl Tricaprylate is often listed near the middle or end of ingredient lists because it is effective at low concentrations.
- It is compatible with both oil-based and emulsion (cream/lotion) formulas.
- This ingredient is not the same as resveratrol — it is a modified ester designed for better performance.
