Vitamin C Reinvented: The Serums That Won’t Oxidize
Vitamin C has been a skincare favorite for decades, but many consumers have struggled with formulas that oxidize quickly, turn brown, or irritate sensitive skin. In 2025, brands are solving the stability problem with innovative delivery systems and smarter ingredient cocktails.
SkinCeuticals C E Ferulic remains the industry gold standard with proven results. Tatcha Violet-C Brightening Serum combines 20% vitamin C with mild fruit AHAs for gentle resurfacing. Drunk Elephant C-Firma Fresh Day Serum is newly reformulated with a two-part system that activates on demand for maximum potency.
Dermatologists recommend applying stabilized vitamin C serums in the morning before sunscreen to fight free radicals and boost glow. New packaging and encapsulated technology mean you can finally get all the brightening benefits—without the dreaded rust ring on your shelf.
