Ingredient review
SH-Polypeptide-95
INCI: SH-Polypeptide-95
A synthetic peptide that may help reduce fine lines and improve skin firmness, but more human studies are needed to confirm its effectiveness.
In plain English
SH-Polypeptide-95 is a lab-made chain of amino acids (the building blocks of protein) designed to signal your skin to produce more collagen. Think of it as a tiny messenger that tells your skin cells to work harder at keeping your skin plump and smooth. It's commonly added to anti-aging products like serums and creams.

Quick decision guide
Useful, but context matters
SH-Polypeptide-95 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 SH-Polypeptide-95.
- 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 peptide, specifically a hexapeptide (made of six amino acids), engineered to mimic natural signaling molecules in the skin that stimulate collagen synthesis.
How it works
When applied topically, SH-Polypeptide-95 penetrates the outer layer of the skin and binds to receptors on fibroblasts (collagen-producing cells). This binding triggers a cascade of signals that increase the production of collagen and other structural proteins, helping to reduce the appearance of fine lines and improve skin firmness over time.
Pros
Gentle on skin
SH-Polypeptide-95 has a low irritation risk, making it suitable for sensitive skin types that may not tolerate stronger anti-aging ingredients like retinol.
Targeted collagen 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
Gradual results
Unlike some active ingredients, SH-Polypeptide-95 works slowly. You may need to use it consistently for several weeks to notice visible improvements.
Limited human evidence
While lab studies are promising, there are fewer large-scale human trials confirming its efficacy compared to more established anti-aging ingredients like retinoids.
Best for
- Adults looking to reduce early signs of aging
- Those with sensitive skin seeking a gentle anti-aging option
Use caution if
- Individuals allergic to synthetic peptides (rare)
- Those expecting immediate or dramatic results
Usage tips
Safety summary
SH-Polypeptide-95 is considered safe for topical use in cosmetics at typical concentrations. It has a low risk of irritation or allergic reaction, though patch testing is recommended for those with very sensitive skin.
Research notes
In vitro studies show SH-Polypeptide-95 can stimulate collagen production in skin cells. Small clinical trials suggest improvements in skin firmness and wrinkle depth, but larger, longer-term studies are needed to confirm these effects in diverse populations.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved as a cosmetic ingredient in the US and EU. Not classified as a drug, so anti-aging claims are limited to cosmetic benefits.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced in controlled lab environments, reducing the environmental impact associated with harvesting natural ingredients.
Good to know
- Peptides are often listed as 'polypeptide' or 'hexapeptide' followed by a number; SH-Polypeptide-95 is one specific variant.
- It can be combined with other peptides or antioxidants for enhanced anti-aging benefits.
