Ingredient review
Dimyristoyl Glyceryl Ascorbate
INCI: Dimyristoyl Glyceryl Ascorbate
A gentle, stable vitamin C derivative that brightens skin and fights free radicals without the irritation of pure L-ascorbic acid.
In plain English
Dimyristoyl Glyceryl Ascorbate is a modified form of vitamin C that has been chemically linked to fatty acids so it stays stable in formulas and can penetrate skin more easily. Unlike pure vitamin C (L-ascorbic acid), it doesn't break down quickly when exposed to air or light, and it's much less likely to sting or irritate sensitive skin. Once inside the skin, enzymes naturally clip off the fatty acid parts, releasing active vitamin C to work its brightening and antioxidant magic.

Quick decision guide
Easy yes for most routines
Dimyristoyl Glyceryl Ascorbate 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 Dimyristoyl Glyceryl Ascorbate.
- 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 vitamin C (ascorbic acid) where two myristic acid (a fatty acid) molecules are attached via a glycerol bridge. This makes the molecule oil-soluble and highly stable in formulations.
How it works
After application, skin enzymes cleave the fatty acid chains, releasing free ascorbic acid. The free vitamin C then acts as a potent antioxidant, neutralizing free radicals, inhibiting melanin production (brightening), and supporting collagen synthesis.
Pros
Gentle on skin
Unlike pure L-ascorbic acid, this derivative does not require a low pH to work, so it rarely causes stinging or redness, making it ideal for sensitive skin.
Excellent stability
It resists oxidation from air and light much better than pure vitamin C, so products stay effective longer on your shelf.
Cons and cautions
Slower conversion
Because it must be enzymatically converted to active vitamin C in the skin, results may take longer to appear compared to using pure L-ascorbic acid.
Less research
Compared to well-studied forms like L-ascorbic acid or ascorbyl glucoside, there are fewer published studies specifically on dimyristoyl glyceryl ascorbate.
Best for
- Anyone seeking antioxidant protection without irritation
- People with sensitive or reactive skin who can't tolerate pure vitamin C
- Those looking for a stable vitamin C option that doesn't require a low pH formula
Use caution if
- Those wanting the fastest, most potent vitamin C effect (pure L-ascorbic acid may be better)
Usage tips
Safety summary
Considered safe for cosmetic use at typical concentrations. It is non-irritating and non-sensitizing in standard tests. No known toxicity or safety concerns have been reported.
Research notes
Clinical and laboratory studies show it effectively delivers vitamin C to the skin, providing antioxidant and brightening benefits. However, direct head-to-head comparisons with other vitamin C derivatives are limited.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Approved for cosmetic use globally, including by the U.S. FDA (as a cosmetic ingredient) and under EU cosmetics regulation.
- Common uses
- Serums, Moisturizers, Eye creams
- Environmental note
- The myristic acid used is typically derived from plant sources like coconut or palm oil; look for sustainably sourced palm oil if that is a concern.
Good to know
- This ingredient is often listed near the middle or end of ingredient lists because effective concentrations are low.
- It pairs well with vitamin E and ferulic acid for enhanced antioxidant power.
