Ingredient review
SH-Polypeptide-70
INCI: SH-Polypeptide-70
SH-Polypeptide-70 is a lab-made peptide that may help firm skin and soften lines, but research is still early.
In plain English
SH-Polypeptide-70 is a short chain of amino acids (the building blocks of protein) made in a lab. When applied to skin, it signals cells to produce more collagen and elastin, which are the proteins that keep skin plump and springy. Think of it as a tiny messenger that tells your skin to act younger. Because it's synthetic, it's very pure and less likely to cause reactions than some natural extracts.

Quick decision guide
Useful, but context matters
SH-Polypeptide-70 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-70.
- 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
A synthetic peptide, specifically a short chain of 70 amino acids, designed to mimic natural signaling proteins in the skin.
How it works
It binds to receptors on skin cells and triggers a cascade that boosts collagen and elastin synthesis, helping to improve skin firmness and reduce the depth of wrinkles over time.
Pros
Gentle anti-aging support
Unlike strong actives like retinol, SH-Polypeptide-70 is unlikely to cause peeling or redness, making it a good option for sensitive skin types.
Targets collagen production
It works at a cellular level to encourage your skin to make more collagen, which is key for maintaining a youthful appearance.
Cons and cautions
Slow to show results
Peptides generally require consistent use over several months before you see visible changes in firmness or wrinkles.
Limited research
Compared to well-studied peptides like Matrixyl, SH-Polypeptide-70 has fewer published studies, so its effectiveness is less certain.
Best for
- Adults looking for a gentle anti-aging ingredient
- Those with sensitive skin who want to avoid strong retinoids
Use caution if
- Anyone with a known allergy to synthetic peptides (rare)
Usage tips
Safety summary
SH-Polypeptide-70 is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in available literature.
Research notes
Evidence for SH-Polypeptide-70 is primarily based on in vitro studies and manufacturer data. Peer-reviewed human trials are scarce, so its efficacy is supported more by analogy to other peptides than by direct clinical proof.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on formulations
- Regulatory status
- Approved for cosmetic use in the US, EU, and other major markets as a skin conditioning agent.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide, its production has a lower environmental footprint than harvesting natural ingredients, but it is not biodegradable in water systems.
Good to know
- Peptides work best when combined with other antioxidants like vitamin C or niacinamide.
- SH-Polypeptide-70 is often listed near the end of ingredient lists because it's effective at low concentrations.
