Regulatory pathway (cosmetic, device, pharmaceutical)
G_REGULATORY_PATHWhat does this word mean?
The legal route a substance follows based on its intended use, which determines its regulatory requirements, permitted claims and evidence standards.
Expanded note
This is one of the site's highest-priority red lines. In most markets a cosmetic ingredient is regulated after the fact through prohibited and restricted ingredient lists plus labelling and claims rules, and the concept of approval simply does not exist, whereas an injectable product follows the device or pharmaceutical route with a licence number and defined indications. The same PDRN therefore has entirely different determination criteria, permitted claims and evidence requirements across the two routes, and the generic phrasing that PDRN is approved must never be used.
Not a generic example.
Korea illustrates this best: PDRN injectables follow the medical device route with licence number Jeheo 14-825, and searching the MFDS pharmaceutical database nedrug by ingredient full name returns zero records. It never took the pharmaceutical route in the first place, which is a different thing from not being approved.

Educational reference only. This site does not provide medical advice, treatment courses, injection counts, clinic recommendations or price recommendations.
PDRN is not approved by the FDA for injection or any therapeutic use. Topical and injectable PDRN are parallel facts under different regulatory pathways and must not be directly equated.
PN is not PDRN. Evidence grades are labelled on every factual element; in vitro and animal research is never described as clinical efficacy.
