Ingredient review
Tripeptide-67
INCI: Tripeptide-67
Tripeptide-67 is a lab-made peptide that may help firm skin and soften fine lines, though research is still early compared to more established peptides.
In plain English
Tripeptide-67 is a tiny protein fragment made of three amino acids. In skincare, it's added to products like serums and creams with the idea that it can signal skin cells to produce more collagen and elastin, which are the building blocks that keep skin plump and firm. Think of it as a messenger that tells your skin to act younger. Because it's a synthetic ingredient, it's designed to be stable and gentle, but its effects are subtle and build over time with regular use.

Quick decision guide
Useful, but context matters
Tripeptide-67 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 Tripeptide-67.
- 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
Tripeptide-67 is a synthetic peptide composed of three amino acids (glycine, histidine, and lysine are common in similar peptides, but the exact sequence is proprietary). It is manufactured in a lab to mimic naturally occurring peptide signals in the skin.
How it works
When applied topically, Tripeptide-67 is thought to penetrate the outer layer of skin and bind to receptors on fibroblasts (the cells that make collagen). This binding may trigger a signaling cascade that encourages increased collagen and elastin production, leading to firmer, more resilient skin over time. It also may help reduce the breakdown of existing collagen.
Pros
Gentle on skin
Tripeptide-67 has a low irritation and comedogenic risk, making it suitable for sensitive skin types and daily use without causing breakouts or redness.
Supports collagen production
By signaling skin cells to produce more collagen, it helps maintain skin structure and may slow visible signs of aging over time.
Cons and cautions
Subtle effects
Unlike retinoids or vitamin C, Tripeptide-67's benefits are mild and take consistent use over several weeks to become noticeable. It is not a quick fix.
Limited research
Compared to more established peptides, there is less published peer-reviewed research specifically on Tripeptide-67, so its efficacy is less certain.
Best for
- People looking for a gentle anti-aging ingredient to support skin firmness
- Those with sensitive or reactive skin who want to avoid stronger actives like retinol
Use caution if
- Anyone expecting dramatic, instant results (peptides work slowly)
- Those with a known allergy to synthetic peptides (rare)
Usage tips
Safety summary
Tripeptide-67 is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential. No significant safety concerns have been reported in available literature or by regulatory bodies.
Research notes
Research on Tripeptide-67 specifically is limited. Most evidence comes from manufacturer studies and general peptide science. Peptides as a class have moderate support for anti-aging benefits, but individual peptides vary in efficacy.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on products
- Regulatory status
- Approved as a cosmetic ingredient in the US, EU, and other major markets. It is not classified as a drug and cannot claim to treat or cure skin conditions.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- As a synthetic peptide, its production involves chemical synthesis, which has a moderate environmental footprint. It is not known to bioaccumulate or harm aquatic life at typical use levels.
Good to know
- Peptides are fragile; avoid using them with very low pH products (like strong AHAs) in the same routine to prevent degradation
- Tripeptide-67 is often combined with other peptides in a formula for a broader anti-aging effect
