Ingredient review
Potato SH-Polypeptide-11
INCI: POTATO SH-POLYPEPTIDE-11
A gentle, plant-derived peptide that may help support skin structure, but research is still limited.
In plain English
This is a small protein fragment (peptide) made from potatoes. In skincare, peptides act like little messengers that tell skin cells to produce more collagen and elastin, which are the proteins that keep skin firm and bouncy. Think of it as a gentle signal to your skin to keep its support system strong.

Quick decision guide
Useful, but context matters
Potato SH-Polypeptide-11 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 Potato SH-Polypeptide-11.
- 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
Potato SH-Polypeptide-11 is a synthetic peptide derived from potato protein. It is designed to mimic natural signaling peptides that encourage collagen production in the skin.
How it works
When applied topically, this peptide is thought to bind to receptors on skin cells, triggering a cascade that boosts collagen and elastin synthesis. Over time, this can help improve skin firmness and reduce the appearance of fine lines.
Pros
Gentle on skin
Low irritation risk makes it suitable for sensitive skin types, unlike some stronger anti-aging actives.
Plant-based origin
Derived from potatoes, offering a vegan-friendly alternative to animal-derived peptides.
Cons and cautions
Limited research
Most evidence comes from lab studies or small trials; large-scale human studies are lacking.
Subtle effects
Results are typically gradual and subtle, not a quick fix for deep wrinkles.
Best for
- Anyone looking for gentle anti-aging support
- Those who prefer plant-derived ingredients
Use caution if
- Those with potato allergies (rare, but possible)
- Anyone seeking immediate or dramatic results
Usage tips
Safety summary
Potato SH-Polypeptide-11 is considered safe for topical use with a low risk of irritation or allergy. As with any new ingredient, patch testing is recommended for those with sensitive skin or known allergies.
Research notes
Early research suggests potato-derived peptides can stimulate collagen production in cell cultures, but clinical evidence in humans is still emerging. More robust studies are needed to confirm efficacy.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US; not a drug ingredient.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Potato-derived peptides are a renewable, plant-based resource with a lower environmental footprint compared to some synthetic alternatives.
Good to know
- Peptides work best when combined with other anti-aging ingredients like antioxidants
- Store products containing peptides away from direct sunlight and heat to maintain stability
