Ingredient review
Sodium Dimyristoyl Glyceryl Ascorbate
INCI: Sodium Dimyristoyl Glyceryl Ascorbate
A gentle, stabilized vitamin C derivative that brightens skin and fights free radicals without the sting of pure ascorbic acid.
In plain English
This is a special version of vitamin C that has been chemically modified to make it more stable and less irritating. Unlike plain vitamin C (ascorbic acid), which can break down quickly in light and air and sometimes cause stinging, this form stays active longer and is gentler on sensitive skin. It also dissolves in oil, so it can get deeper into your skin's layers to work its magic.

Quick decision guide
Easy yes for most routines
Sodium 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 Sodium 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
Sodium Dimyristoyl Glyceryl Ascorbate is a semi-synthetic derivative of vitamin C (ascorbic acid). It is created by attaching two fatty acid chains (myristic acid) and a glycerin backbone to the vitamin C molecule, making it oil-soluble and much more stable than pure ascorbic acid.
How it works
Once applied to the skin, enzymes naturally break down the fatty acid attachments, releasing active vitamin C. This free vitamin C then acts as a powerful antioxidant, neutralizing free radicals from UV and pollution. It also inhibits the enzyme tyrosinase, which helps reduce dark spots and uneven skin tone, and boosts collagen production for firmer skin.
Pros
Superior stability
Unlike pure vitamin C, this derivative resists oxidation from air and light, so your product stays effective longer on the shelf.
Gentle on skin
It has a near-neutral pH and doesn't cause the stinging or redness that some people experience with L-ascorbic acid, making it ideal for sensitive skin.
Cons and cautions
Less research backing
While promising, there are fewer clinical studies on this specific derivative compared to decades of research on L-ascorbic acid, so its long-term benefits are less documented.
Potentially lower potency
Because it must be converted into active vitamin C by the skin, it may deliver a weaker antioxidant effect than an equal concentration of pure ascorbic acid.
Best for
- Anyone looking for a gentle vitamin C option that won't sting
- People with sensitive or reactive skin who want antioxidant benefits
- Those seeking a stable vitamin C that works well in oil-based formulas
Use caution if
- Those who prefer the proven potency of pure L-ascorbic acid and can tolerate its acidity
Usage tips
Safety summary
Sodium Dimyristoyl Glyceryl Ascorbate is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, making it suitable for most skin types, including sensitive skin. No significant safety concerns have been reported in cosmetic concentrations.
Research notes
Research on this derivative is moderate. Studies show it effectively delivers vitamin C to the skin, provides antioxidant activity, and inhibits melanin production. However, direct head-to-head comparisons with L-ascorbic acid are limited. Most evidence comes from ingredient supplier studies and small clinical trials.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Approved for cosmetic use in the US, EU, and most major markets. No special restrictions.
- Common uses
- Serums, Moisturizers, Eye creams
- Environmental note
- Synthesized from plant-derived myristic acid and glycerin, but the manufacturing process involves chemical modification. Not typically associated with significant environmental concerns.
Good to know
- This ingredient is often listed near the middle or end of an ingredient list because effective concentrations are low.
- It pairs well with vitamin E and ferulic acid for enhanced antioxidant protection.
