Ingredient review
Tripeptide-62
INCI: Tripeptide-62
A synthetic peptide that may help support collagen and improve skin firmness, but human data is still limited.
In plain English
Tripeptide-62 is a tiny protein fragment made of three amino acids. In skincare, it's used to signal skin cells to behave more youthfully, potentially boosting collagen and reducing the look of wrinkles. Think of it as a messenger that tells your skin to tighten up and smooth out, but it's not a miracle worker and works best over time with consistent use.

Quick decision guide
Useful, but context matters
Tripeptide-62 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-62.
- 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-62 is a synthetic peptide, meaning it's a short chain of amino acids (the building blocks of proteins) created in a lab. It belongs to a class of peptides often called 'signal peptides' because they mimic natural fragments of collagen or other skin proteins, sending signals to skin cells to produce more collagen and elastin.
How it works
When applied to the skin, Tripeptide-62 is thought to penetrate the outer layer and interact with fibroblast cells. It may bind to specific receptors that trigger the production of collagen and other extracellular matrix components. This can help improve skin firmness, elasticity, and reduce the appearance of fine lines over weeks of regular use.
Pros
Gentle on skin
Tripeptide-62 has a very low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin types.
Targeted anti-aging support
It specifically signals collagen production, which can help improve skin firmness and reduce fine lines over time without harsh side effects.
Cons and cautions
Limited evidence
Most supporting data comes from lab or animal studies; robust human clinical trials are scarce, so results may be subtle.
Slow and subtle results
Unlike retinoids or AHAs, peptides work gradually. Users may need to wait 8–12 weeks to see noticeable improvements.
Best for
- People looking for a gentle anti-aging ingredient
- Those with sensitive skin who cannot tolerate retinol or acids
Use caution if
- Anyone seeking immediate or dramatic results
- Those on a very tight budget, as peptide serums can be pricey
Usage tips
Safety summary
Tripeptide-62 is considered safe for cosmetic use at typical concentrations. No significant irritation, sensitization, or toxicity has been reported in available safety assessments.
Research notes
Evidence is primarily from in vitro studies showing collagen stimulation. Human studies are limited but suggest modest improvements in skin firmness and wrinkle depth with consistent use over 8–12 weeks.
Common label clues
- Typical concentration
- 0.001% to 0.1% in leave-on products
- Regulatory status
- Approved as a cosmetic ingredient in the EU, US, and other major markets. Not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- Synthetically produced, so no direct plant or animal sourcing concerns. Biodegradability data is not publicly available.
Good to know
- Tripeptide-62 is often combined with other peptides or antioxidants in anti-aging formulas.
- It is stable in most pH ranges but avoid using with very low pH (under 4.0) products immediately before or after.
