That concern is simplistic, Clinuvel CEO Dr. Philippe Wolgen mentioned, since darker pigmentation is usually a symptom of melanoma and never its underlying trigger.

Wolgen mentioned the corporate hopes to make a topical product for wider consumption; in his opinion, a tablet or a drink can be pointless and harmful as a result of threat of an overdose. Moreover, it is going to be one other six to 12 months earlier than the FDA finishes reviewing Scenesse for restricted use.
