What makes a Medik8 Vitamin C unique?

Vitamin C is notoriously unstable, meaning it can quickly lose 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 carefully stabilise to ensure optimal potency and maximum visible results from first to last drop. We believe the perfect vitamin C formula does exist – and it’s stable, feels amazing on the skin and delivers impressive benefits minus the irritation.
