Series: Claims Literacy

If the clinic cannot write down device name, depth or energy band, pass count, and the downtime that matches that plan, you do not have a protocol. You have a brand name and a hope.

Growth factors and PDRN ride real biomedical research language into retail serums. Ingredient-level science is not finished-product proof. Here is how to separate the lab story from the dropper.

‘Clinically proven’ is not a regulated gold medal. It can mean a careful trial—or a tiny, short, brand-funded test of a vague endpoint. Here is how to read the phrase without handing it your wallet.

Exosomes are real biological messengers. Topical and aesthetic marketing often outruns finished-product evidence and regulatory reality. Mechanism interest is not the same as a licensed, proven beauty outcome.

The label sounds decisive. The evidence may not be. Compare formula, claims, testing, use, cost, and burden instead of letting two words make the purchase for you.

Beauty evidence belongs to a specific object: ingredient, mechanism, finished formula, regimen, or outcome. Learn what each level can support—and what it cannot legitimately prove.
