Ingredient review
SH-Polypeptide-80
INCI: SH-Polypeptide-80
SH-Polypeptide-80 is a lab-made peptide that may help support firmer-looking skin, but research is still emerging.
In plain English
SH-Polypeptide-80 is a short chain of amino acids (the building blocks of proteins) made in a lab. In skincare, it's added to products to signal skin cells to behave more like younger, healthier skin. Think of it as a tiny messenger that tells your skin to produce more collagen and elastin, which are the proteins that keep skin plump and bouncy. Because it's a synthetic peptide, it's designed to be stable and effective in formulas, but it's still a newer ingredient with limited long-term studies.

Quick decision guide
Useful, but context matters
SH-Polypeptide-80 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-80.
- 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-80 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.
How it works
When applied topically, SH-Polypeptide-80 is thought to mimic natural peptide signals that encourage skin cells to ramp up production of collagen and other structural proteins. This can help improve skin firmness and reduce the appearance of fine lines over time.
Pros
Targeted anti-aging support
SH-Polypeptide-80 is designed to send specific signals to skin cells to boost collagen, which can help reduce fine lines and improve firmness over time.
Low irritation profile
Because it's a synthetic peptide, it's generally non-irritating and suitable for most skin types, including sensitive skin.
Cons and cautions
Limited research
There are few published human studies on SH-Polypeptide-80 specifically, so its long-term efficacy and safety are not as well-documented as some other peptides.
Variable effectiveness
The results you see can depend heavily on the product formulation, concentration, and how well the peptide is delivered into the skin.
Best for
- Anyone looking to support firmer, more youthful-looking skin
- People with dry or mature skin who want to boost collagen production
Use caution if
- Those with known allergies to synthetic peptides (rare)
Usage tips
Safety summary
SH-Polypeptide-80 is considered safe for use in cosmetics at typical concentrations. It has a low risk of irritation and is not known to be comedogenic. However, long-term safety data specific to this peptide is limited.
Research notes
Research on SH-Polypeptide-80 is still emerging. While peptides in general have a solid body of evidence supporting their anti-aging benefits, specific studies on this exact peptide are scarce. Most evidence comes from ingredient manufacturer data and broader peptide research.
Common label clues
- Typical concentration
- Typically used at very low concentrations, often below 1%
- Regulatory status
- SH-Polypeptide-80 is a cosmetic ingredient regulated by the FDA as part of a cosmetic product. It is not a drug and is not intended to treat or prevent any medical condition.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide, its production involves chemical synthesis, which may have a moderate environmental footprint compared to naturally derived alternatives.
Good to know
- Peptides like SH-Polypeptide-80 are often combined with other anti-aging ingredients like vitamin C or retinol for enhanced benefits.
- Store products containing peptides away from direct sunlight and heat to maintain stability.
