AHK-Cu

Known published concerns and unanswered questions are kept separate so absence of evidence is never presented as reassurance.

Form describes the specific product; route describes how it reaches the body. These are sourced descriptions, not instructions.

Topical use describes the scoped cosmetic context; it is not a treatment recommendation. No approved injectable route was identified.

Status applies to a product, formulation, route, population, and use. It does not apply to a name in the abstract.
