Peptide ChooserPeptides for skin, compared with the proven options.
Tretinoin is the only option on this page the FDA has approved for fine wrinkles, and it needs a prescription. Peptide creams and serums are cosmetics: legal to sell without approval, judged on small studies of their own. None is a drug and none needs a prescription.
