Press four or five drops over clean, dry skin in the morning. The 15% L-ascorbic acid, vitamin E, and ferulic acid support antioxidant defense and help with dullness and uneven tone, while sunscreen remains the essential melasma step.
Start every other morning if pregnancy has made your skin reactive. Oxidized vitamin C will not earn extra credit, so keep the bottle closed, away from heat and light, and replace it if it turns very dark brown.
