Ingredient review
Myristoyl Succinoyl Atelocollagen
INCI: MYRISTOYL SUCCINOYL ATELOCOLLAGEN
A modified collagen that may help improve skin firmness and moisture, but human studies are limited.
In plain English
This ingredient is a lab-modified version of collagen, a protein that naturally supports skin structure. The modification helps it stick to skin better and resist breakdown. It's meant to temporarily plump and firm the skin by forming a light film and attracting moisture.

Quick decision guide
Useful, but context matters
Myristoyl Succinoyl Atelocollagen 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 Myristoyl Succinoyl Atelocollagen.
- 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
Myristoyl Succinoyl Atelocollagen is a semi-synthetic peptide derived from collagen. The myristoyl and succinoyl groups are added to improve its stability and ability to bind to the skin's surface.
How it works
It forms a thin, flexible film on the skin that helps reduce water loss and gives a temporary tightening effect. The collagen peptides may also signal skin cells to produce more of their own collagen, though this effect is less proven in topical use.
Pros
Gentle and low irritation
Unlikely to cause redness or breakouts, making it suitable for sensitive skin types.
Immediate smoothing effect
Forms a film that can make skin feel firmer and look smoother right after application.
Cons and cautions
Limited human research
Most evidence comes from lab studies; robust human trials are scarce, so results may vary.
Temporary results
The firming effect is not permanent and fades once the product is washed off or the ingredient degrades.
Best for
- People looking for a gentle firming ingredient
- Those with dry or mature skin wanting extra hydration
Use caution if
- Anyone allergic to collagen or bovine-derived ingredients
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Rare allergic reactions are possible, especially in individuals with known collagen allergies.
Research notes
In vitro studies suggest collagen peptides can stimulate fibroblast activity, but human data is limited. More rigorous clinical trials are needed to confirm anti-aging benefits.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for cosmetic use in the EU, USA, and other major markets. No specific restrictions.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Collagen is typically sourced from bovine or marine by-products, which can be a sustainability concern. Look for brands that disclose ethical sourcing.
Good to know
- Atelocollagen is collagen with the telopeptide ends removed, which reduces its potential to cause allergic reactions.
- This ingredient is often found in luxury anti-aging products.
