Skin product or medicine

Ask what the product is meant to do.

Before weighing any results, ask which you have been offered: a skin product or a medicine. Then ask what claim is being made for that exact product.

Purpose matters as well as form

As of September 30, 2026, ordinary cosmetics could be sold without FDA (the US Food and Drug Administration) approval beforehand; colour additives have separate approval rules.

Drug rules apply when a skin product is intended to treat disease or change how the skin is built or works, even if it also changes how skin looks.

FDA places a claim to increase skin collagen on the drug side of that line. Collagen is among the proteins that give skin strength.

Keep other offers in their own conversation

If another treatment is offered at the same visit, ask what it is meant to do and how it works. Request the evidence and rules for that treatment separately.

You can ask to talk only about the peptide offer today. A shared appointment does not need to become a shared decision about everything mentioned.

If the label says copper peptide

Beside the full ingredient name, write down how it would be used and what it is meant to do.
