Ingredient review
Potato SH-Oligopeptide-1
INCI: Potato SH-Oligopeptide-1
A gentle, plant-derived peptide that may help support skin firmness and a more youthful look, though research is still emerging.
In plain English
This is a small protein fragment (a peptide) made from potato. In skincare, peptides act like little messengers that can signal skin cells to behave in certain ways. Potato SH-Oligopeptide-1 is thought to help support the skin's natural structure, potentially making it feel firmer and look smoother over time. Because it comes from a plant source, it's often appealing to those looking for non-animal-derived ingredients.

Quick decision guide
Useful, but context matters
Potato SH-Oligopeptide-1 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-Oligopeptide-1.
- 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-Oligopeptide-1 is a synthetic peptide derived from potato protein. It belongs to a class of ingredients called signal peptides, which are short chains of amino acids designed to mimic natural peptides in the skin.
How it works
In a cosmetic product, this peptide is believed to interact with skin cells to encourage the production of collagen and other supportive proteins. By doing so, it may help improve skin firmness and reduce the appearance of fine lines over consistent use.
Pros
Plant-derived peptide
Sourced from potato, making it a vegan-friendly alternative to animal-derived peptides.
Low irritation potential
Generally well-tolerated, even for sensitive skin, with a low risk of irritation or clogged pores.
Cons and cautions
Limited research
Most evidence comes from lab studies or small trials; large-scale human studies are lacking.
Subtle effects
Results are gradual and may not be as dramatic as more established peptides or retinoids.
Best for
- Anyone looking for a gentle, plant-based anti-aging ingredient
- Those with normal to dry skin wanting extra firmness support
Use caution if
- Individuals with known potato allergies (rare, but possible)
- Those expecting dramatic, instant results
Usage tips
Safety summary
Potato SH-Oligopeptide-1 is considered safe for topical use in cosmetics. It has a low irritation and comedogenic risk, making it suitable for most skin types. As with any new ingredient, a patch test is recommended for those with sensitive skin or allergies.
Research notes
Research on potato-derived peptides is still in early stages. Preliminary studies suggest potential benefits for skin firmness and collagen support, but more robust clinical trials are needed to confirm efficacy.
Common label clues
- Typical concentration
- Typically used at 0.1–2% in leave-on products
- Regulatory status
- Considered a cosmetic ingredient; not approved as a drug. No specific restrictions in the US or EU when used within safe concentration limits.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Potato-derived peptides are generally considered more sustainable than animal-derived alternatives, though the extraction and synthesis process still requires energy and resources.
Good to know
- Peptides work best when used in a stable formulation with a pH around 5–7.
- Potato SH-Oligopeptide-1 is often combined with other peptides for a synergistic effect.
