Are exosome skincare products regulated as cosmetics or drugs in the US?

Plant-derived exosome extracts marketed with cosmetic-only claims (e.g., 'supports the appearance of skin renewal') are generally treated as cosmetics under FDA 21 CFR Part 700. However, human-derived or clinically framed exosome products may trigger drug or biologics classification. Always have your formulator and a regulatory consultant review your specific ingredient source and claims before launch.
