Ingredient review
SH-Polypeptide-82
INCI: SH-Polypeptide-82
A lab-made peptide that may help support collagen and improve skin firmness, but research is still early and results vary.
In plain English
SH-Polypeptide-82 is a short chain of amino acids (the building blocks of protein) made in a lab. In skincare, it's added to products like serums and creams with the goal of signaling skin cells to produce more collagen and elastin, which can help the skin look firmer and smoother over time. Because it's a synthetic peptide, it's designed to be stable and easily absorbed, but its effects are subtle and not as dramatic as prescription treatments.

Quick decision guide
Useful, but context matters
SH-Polypeptide-82 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-82.
- 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
SH-Polypeptide-82 is a synthetic peptide, meaning it's a man-made chain of amino acids. Peptides are fragments of proteins that can act as signaling molecules in the skin, encouraging processes like collagen production.
How it works
When applied topically, SH-Polypeptide-82 is thought to mimic natural peptide signals that tell skin cells to ramp up collagen and elastin synthesis. This can help improve skin firmness, reduce the depth of fine lines, and support the skin's overall structure. It works slowly and cumulatively, so consistent use over weeks to months is needed to see any benefit.
Pros
Gentle on skin
SH-Polypeptide-82 has a low irritation risk, making it suitable for sensitive skin types that react to stronger anti-aging ingredients.
Supports collagen signaling
It may help stimulate collagen production at a cellular level, which can improve skin firmness and reduce fine lines over time.
Cons and cautions
Subtle effects
Results are mild and take consistent use over several months to notice; it won't dramatically change deep wrinkles.
Limited research
There are few peer-reviewed human studies specifically on SH-Polypeptide-82, so its efficacy is less established compared to ingredients like retinoids.
Best for
- People looking for a gentle anti-aging ingredient
- Those with sensitive skin who cannot tolerate stronger actives like retinol
Use caution if
- Anyone expecting dramatic or fast results
- People on a tight budget, as peptide serums can be pricey
Usage tips
Safety summary
SH-Polypeptide-82 is considered safe for topical cosmetic use at typical concentrations. It has a low irritation and comedogenic risk, and no significant safety concerns have been reported in available literature.
Research notes
Research on SH-Polypeptide-82 is limited. Most evidence comes from in vitro studies and small-scale cosmetic trials. While the concept of peptide signaling is well-supported, specific data on this peptide's efficacy in humans is sparse.
Common label clues
- Typical concentration
- Typically used at 0.5% to 2% in leave-on products
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets as a skin conditioning agent. Not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- As a synthetic peptide, it is produced in controlled lab conditions, which reduces the environmental impact compared to harvesting from natural sources. However, its biodegradability is not well documented.
Good to know
- Peptides work best when combined with other anti-aging ingredients like antioxidants (vitamin C) and sunscreen.
- SH-Polypeptide-82 is often found in high-end anti-aging serums and eye creams.
