Ingredient review
SH-Polypeptide-86
INCI: SH-Polypeptide-86
SH-Polypeptide-86 is a synthetic peptide that may help reduce fine lines by signaling skin cells to produce more collagen, but long-term human data is still limited.
In plain English
SH-Polypeptide-86 is a lab-made protein fragment (a peptide) that acts like a messenger to your skin cells. When applied in a cream or serum, it tells your skin to make more collagen, which is the protein that keeps skin firm and plump. Think of it as a gentle nudge to your skin's natural repair system, not a magic eraser. Results are gradual and vary by person.

Quick decision guide
Useful, but context matters
SH-Polypeptide-86 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-86.
- 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
SH-Polypeptide-86 is a synthetic peptide, meaning it's a short chain of amino acids made in a lab. It belongs to a class of ingredients called signal peptides, which are designed to mimic natural peptides that trigger collagen synthesis in the skin.
How it works
When applied topically, SH-Polypeptide-86 penetrates the outer layer of skin and binds to receptors on fibroblasts (the cells that make collagen). This binding sends a signal to increase collagen production, which can help improve skin firmness, elasticity, and reduce the appearance of fine lines over time.
Pros
Gentle anti-aging
SH-Polypeptide-86 is non-irritating for most skin types, making it a good option for those who find retinol or acids too harsh.
Supports natural collagen
It works by encouraging your skin's own collagen production, which can lead to gradual improvements in firmness and texture without disrupting the skin barrier.
Cons and cautions
Slow results
Unlike stronger ingredients like retinol, SH-Polypeptide-86 requires consistent use over several weeks to see subtle changes, which may not satisfy those seeking quick fixes.
Limited evidence
Most research on signal peptides is sponsored by manufacturers, and independent long-term human studies are scarce, so the full efficacy and safety profile is not yet firmly established.
Best for
- Adults looking for gentle anti-aging support
- Those with sensitive skin who cannot tolerate retinol
Use caution if
- Anyone allergic to synthetic peptides (rare)
- Those expecting instant or dramatic results
Usage tips
Safety summary
SH-Polypeptide-86 is considered safe for topical use in cosmetics at typical concentrations. Irritation and allergic reactions are rare, but patch testing is recommended for those with very sensitive skin. There is no evidence of systemic toxicity from cosmetic use.
Research notes
Evidence for SH-Polypeptide-86 is based on in vitro studies and small clinical trials, often funded by ingredient manufacturers. These suggest it can stimulate collagen synthesis and improve skin firmness, but independent, large-scale human studies are lacking. The ingredient is part of a well-studied class of signal peptides with a reasonable safety profile.
Common label clues
- Typical concentration
- Typically used at 0.5% to 2% in leave-on products
- Regulatory status
- SH-Polypeptide-86 is not specifically regulated as a drug; it is considered a cosmetic ingredient in most countries, including the US and EU, and must meet general safety standards for cosmetics.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide, it is produced in a lab, which avoids harvesting from animal or plant sources. Its environmental impact is low, but manufacturing energy use should be considered.
Good to know
- SH-Polypeptide-86 is often found in high-end anti-aging serums and may be listed alongside other peptides for a synergistic effect.
- It is water-soluble and typically formulated in water-based products.
