Peptides
Peptides are marketed as collagen boosters for aging skin. Even in adults, a large review of the trials found only small effects, with shaky methods behind most of them. And nearly all the halfway-decent data is for peptides you swallow, not creams. Meanwhile, your skin is currently making more collagen than it ever will again, for free. Not harmful. Just a very expensive shrug.
what the evidence says
2026 systematic review and meta-analysis: modest effects, high heterogeneity, sparse topical data. No teen-specific evidence exists.
