Our take
Is Sh-Polypeptide-3 a Good Ingredient?
This growth factor peptide earns a Good rating: it plausibly supports the skin's natural repair processes and helps texture look smoother, and it's a common ingredient in higher-end lines targeting fine lines and general rejuvenation. It falls short of Great because the evidence for those repair claims is still thin relative to better-studied peptides.
What it does
Skin Benefits
It helps skin feel softer and look more polished, for a fresher overall appearance. The effects tend to be subtle, since the evidence behind it is still limited.
Where you'll find it
Uses in Skincare & Cosmetics
You'll find it in serums, essences, and lightweight gels meant for daily smoothing, as well as in moisturizers where it layers easily.
Before you use it
Safety
It's typically low risk in leave-on products and isn't known to cause photosensitivity or clog pores. Sensitive skin may still see mild irritation or an allergic reaction, so a patch test is worthwhile. There are no well-established regulatory restrictions on this class of ingredient.
