The Vitamin C Vault: Global Edition

Every major beauty origin has built its own vitamin C reference. American prestige goes through SkinCeuticals' Duke patent (CE Ferulic) and Sunday Riley's THD ascorbate. Spanish pharmacy turned the ampoule format into a category and built proprietary technology around it (Mesoestetic Energy C Complex matches the Duke ratio at half the price). Korean labs went hard on high-concentration L-ascorbic (By Wishtrend 21.5%). Japanese drugstore made it accessible (Rohto Melano CC). Finnish brands centered Arctic cloudberry (Lumene). French naturopathic prestige did vinotherapy (Caudalie Vinoperfect). Indian D2C undercut everyone (Minimalist 16% at drugstore pricing). The vault. Pick one for daily morning use, pair with daily SPF50, commit for 8-12 weeks.
