Whether a product is a cosmetic, a medical device, a drug, or a research-use-only item changes what it is legally allowed to claim — and how it should be evaluated. The same vial can be marketed very differently depending on the region in which it is sold.
The frameworks worth knowing
MFDS (South Korea), CE marking (EU medical devices), CPNP (EU cosmetic notification), MoCRA (US cosmetics), and the relevant ISO and GMP standards each tell you something specific about classification, manufacturing quality, and permitted claims.
Putting it together
When you cross-reference a manufacturer’s transparency, product classification, and ingredient claims against the actual regulatory landscape, you can quickly see whether the marketing matches what the product is allowed to claim — or whether it is quietly overselling.
