Ingredient review
SH-Polypeptide-110
INCI: SH-Polypeptide-110
SH-Polypeptide-110 is a lab-made peptide that may help support firmer, smoother skin, but research is still early and results vary.
In plain English
SH-Polypeptide-110 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 skin look firmer and reduce fine lines over time. Think of it as a tiny messenger that tells your skin to act a bit younger. Because it's synthetic, it's designed to be stable and gentle, but it's not a quick fix—results take consistent use over weeks or months.

Quick decision guide
Useful, but context matters
SH-Polypeptide-110 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-110.
- 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-110 is a synthetic peptide, meaning it's a man-made chain of amino acids. Peptides are often used in anti-aging products because they can mimic natural signaling molecules in the skin.
How it works
When applied topically, SH-Polypeptide-110 is thought to penetrate the outer layer of skin and signal fibroblasts (cells that produce collagen and elastin) to increase production. This can help improve skin firmness, elasticity, and reduce the appearance of fine lines over time.
Pros
Gentle on skin
SH-Polypeptide-110 has a low irritation risk, making it suitable for sensitive skin types that may react to stronger anti-aging actives like retinol.
Supports skin structure
By signaling collagen production, it may help improve skin firmness and elasticity over time, which is beneficial for aging or lax skin.
Cons and cautions
Slow results
Unlike some active ingredients that show visible changes in weeks, peptides like SH-Polypeptide-110 require consistent use for months before noticeable improvement.
Limited research
There is little published clinical data specifically on SH-Polypeptide-110, so its effectiveness is based more on general peptide science than on this exact compound.
Best for
- Anyone looking for a gentle anti-aging ingredient to support skin firmness
- People with sensitive skin who want a low-irritation option for fine lines
Use caution if
- Those expecting immediate or dramatic results—this is a slow-acting ingredient
Usage tips
Safety summary
SH-Polypeptide-110 is considered safe for cosmetic use with a low risk of irritation or allergic reaction. It is not known to be comedogenic (pore-clogging). As with any new ingredient, patch testing is recommended for those with very sensitive skin.
Research notes
Research on SH-Polypeptide-110 specifically is limited. However, the broader class of signal peptides has moderate evidence supporting their ability to stimulate collagen synthesis in vitro (lab studies). Human studies on similar peptides show modest improvements in skin firmness and wrinkle depth over 8–12 weeks.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on products
- Regulatory status
- SH-Polypeptide-110 is a cosmetic ingredient regulated as a cosmetic raw material. It is not a drug and cannot claim to treat or cure skin conditions. In the EU and US, it is generally considered safe for use in cosmetics at typical concentrations.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide, it is produced in a lab, which reduces the need for animal-derived or plant-sourced raw materials. Its environmental impact is considered low compared to some natural extracts that require harvesting.
Good to know
- Peptides are often listed near the middle or end of an ingredient list, as they are used in small amounts.
- SH-Polypeptide-110 is not the same as copper peptides, which have a different mechanism and color.
