Ingredient review
Pentapeptide-62
INCI: Pentapeptide-62
Pentapeptide-62 is a lab-made peptide that may help improve skin firmness and reduce fine lines, but more independent human studies are needed.
In plain English
Pentapeptide-62 is a short chain of five amino acids (the building blocks of proteins) made in a lab. When applied to skin, it's thought to signal skin cells to produce more collagen and elastin, which are proteins that keep skin plump and firm. Think of it as a tiny messenger that tells your skin to act younger. It's commonly found in anti-aging serums and eye creams.

Quick decision guide
Useful, but context matters
Pentapeptide-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 Pentapeptide-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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic pentapeptide, meaning it consists of five amino acids linked together. It is designed to mimic naturally occurring peptide fragments that trigger collagen production.
How it works
Pentapeptide-62 is believed to penetrate the outer layer of skin and bind to receptors on fibroblasts (the cells that make collagen). This binding may stimulate the production of collagen and elastin, helping to improve skin firmness and reduce the appearance of fine lines and wrinkles over time.
Pros
Gentle on skin
Pentapeptide-62 has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin.
Targets firmness
Unlike some peptides that focus only on wrinkle depth, this one is specifically marketed to support skin firmness and elasticity, which can help with sagging.
Cons and cautions
Limited research
Most evidence comes from manufacturer studies rather than independent, peer-reviewed human trials, so the real-world effectiveness is less certain.
Slow results
Peptides work gradually, and it may take several weeks to months of consistent use to see visible changes, which can be frustrating for those seeking quick fixes.
Best for
- Adults looking for a gentle anti-aging ingredient
- People with fine lines or loss of firmness who want a non-irritating option
Use caution if
- Individuals with known allergies to synthetic peptides (rare)
Usage tips
Safety summary
Pentapeptide-62 is considered safe for topical cosmetic use at typical concentrations. Irritation and allergic reactions are rare. As with any new ingredient, a patch test is recommended for those with very sensitive skin.
Research notes
Evidence for Pentapeptide-62 is primarily based on in vitro studies and manufacturer-sponsored clinical trials showing improvements in skin firmness and wrinkle reduction. Independent peer-reviewed human studies are limited, so the evidence level is moderate.
Common label clues
- Typical concentration
- 0.5% to 2%
- Regulatory status
- Approved as a cosmetic ingredient in the US and EU; not classified as a drug.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- Synthetic peptides are produced in controlled lab settings, which reduces environmental impact compared to harvesting from natural sources.
Good to know
- Pentapeptide-62 is often combined with other peptides or antioxidants in formulations for enhanced effects.
- It is water-soluble, so it works well in serums and lightweight gels.
