Ingredient review
Caffeoyl Oligopeptide-77
INCI: Caffeoyl Oligopeptide-77
A synthetic peptide that may help firm skin and soften lines, but research is still early and results vary.
In plain English
Caffeoyl Oligopeptide-77 is a lab-made ingredient that combines a small protein fragment (peptide) with a compound from coffee (caffeoyl group). In skincare, it's used to signal skin cells to produce more collagen and elastin, which are the proteins that keep skin plump and springy. Think of it as a gentle messenger that tells your skin to firm up, but it's not a magic eraser—results are subtle and take time.

Quick decision guide
Useful, but context matters
Caffeoyl Oligopeptide-77 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 Caffeoyl Oligopeptide-77.
- 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 (a short chain of amino acids) that has been chemically linked to a caffeoyl group, which is derived from caffeic acid found in coffee. This combination is designed to improve the peptide's stability and ability to penetrate the skin.
How it works
When applied topically, Caffeoyl Oligopeptide-77 is thought to mimic natural signaling molecules in the skin. It may bind to receptors on fibroblasts (the cells that make collagen) and encourage them to produce more collagen and elastin. This can help improve skin firmness and reduce the depth of fine lines over time, though the effect is gradual and depends on consistent use.
Pros
Gentle on skin
Caffeoyl Oligopeptide-77 has a low irritation risk, making it suitable for most skin types, including sensitive skin, unlike stronger anti-aging ingredients like retinol.
Supports collagen production
It may help stimulate your skin's own collagen and elastin production, which can improve firmness and reduce fine lines over time.
Cons and cautions
Limited research
Most evidence comes from lab studies or small trials; large-scale human studies are lacking, so the real-world effectiveness is not fully proven.
Subtle results
Don't expect overnight changes. This ingredient works gradually, and you may need to use it for several months to see any noticeable improvement.
Best for
- People looking for a gentle anti-aging ingredient with low irritation potential
- Those wanting to complement stronger actives like retinol or vitamin C
Use caution if
- Anyone seeking fast, dramatic results (this ingredient works slowly)
- Individuals with very sensitive skin who react to many peptides (though rare)
Usage tips
Safety summary
Caffeoyl Oligopeptide-77 is considered safe for topical use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, and no significant safety concerns have been reported in available studies.
Research notes
Research on Caffeoyl Oligopeptide-77 is still emerging. Preliminary studies suggest it may stimulate collagen synthesis, but most evidence is from in vitro (lab) or small-scale human trials. More robust clinical studies are needed to confirm its efficacy and compare it to established anti-aging peptides.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic ingredient, its environmental impact is tied to the manufacturing process. No known bioaccumulation or ecotoxicity concerns at typical use levels.
Good to know
- Caffeoyl Oligopeptide-77 is often found in premium anti-aging products due to its higher cost.
- It is not related to caffeine in terms of stimulating effects—it does not wake up skin or reduce puffiness.
