Our take
Is Sh-Polypeptide-1 a Good Ingredient?
Good, because as a recombinant growth factor it may help promote skin renewal and improve the appearance of aging skin, and it's considered a premium ingredient found in advanced anti-aging formulations. The evidence behind it isn't extensive enough to reach Great, but the plausible mechanism and widespread premium use support Good.
