Ingredient review
Oligopeptide-114 Acetate
INCI: Oligopeptide-114 Acetate
A synthetic peptide that may help improve skin firmness and reduce fine lines, but human research is still limited.
In plain English
Oligopeptide-114 Acetate is a lab-made peptide—a short chain of amino acids—that is added to skincare products to signal skin cells to produce more collagen and elastin. Think of it as a tiny messenger that tells your skin to act younger and firmer. Because it's a large molecule, it's usually used in very small amounts and needs a well-formulated delivery system to work effectively.

Quick decision guide
Useful, but context matters
Oligopeptide-114 Acetate 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 Oligopeptide-114 Acetate.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A synthetic peptide (short protein fragment) modified with an acetate group for stability, designed to mimic natural signaling molecules that encourage collagen production in the skin.
How it works
When applied topically, the peptide is thought to bind to receptors on skin cells, triggering a cascade of signals that boost collagen and elastin synthesis. This can help improve skin firmness, reduce the appearance of fine lines, and support the skin's structural matrix over time.
Pros
Gentle on skin
Oligopeptide-114 Acetate has a low irritation risk, making it suitable for most skin types, including sensitive skin.
Targeted anti-aging support
It specifically signals collagen production, which can help improve skin firmness and reduce fine lines over time.
Cons and cautions
Limited human evidence
Most research on this specific peptide is from lab studies or small trials; large-scale human studies are lacking.
Slow, subtle results
Peptides work gradually, and visible improvements may take weeks to months of consistent use.
Best for
- Adults looking to improve skin firmness and reduce early signs of aging
- Those who tolerate peptides well and want a gentle anti-aging option
Use caution if
- Individuals with known allergies to synthetic peptides (rare)
- Those expecting immediate or dramatic results
Usage tips
Safety summary
Oligopeptide-114 Acetate is considered safe for topical use in cosmetics at typical concentrations. Irritation and allergic reactions are rare. As with any new ingredient, a patch test is recommended.
Research notes
Evidence for Oligopeptide-114 Acetate is primarily based on in vitro studies and small clinical trials showing potential collagen-boosting effects. More robust human studies are needed to confirm efficacy and optimal usage.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used as directed. Not classified as a drug.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced in labs, which reduces the need for animal-derived ingredients and has a lower environmental footprint than some natural extracts.
Good to know
- Peptides are often listed near the end of ingredient lists because they are effective at very low concentrations.
- Store peptide products away from heat and light to maintain stability.
