Vitamin C is notoriously unstable, meaning it quickly loses its effectiveness when it comes into contact with air, light and heat. That’s why we only formulate with proven forms of vitamin C, which we expertly stabilize to ensure optimal potency and maximum visible results until the last drop. We believe the perfect vitamin C formula does exist - and it’s stable, feels amazing on the skin and delivers impressive visible benefits without causing irritation.
