Interested in making a cream with active ingredient from icthamol, azalaic acid to treat acne. But the problem is 1. Suppose that if you want to register FDA for use in cosmetics, these substances are classified as drugs or cosmetics. Is there a prohibition to take note or not? For example, azalaic acid will tell you that it's a drug, but you can use Azeloil diglyconate instead, so I'm a bit confused. 2. How can I usually check which substance is a drug or cosmetic group? no Or do I have to call and ask the FDA? Personally? For example, tar is a medicine or cosmetic, etc. Thank you for your advice.
