At Medik8, we offer an extensive range of vitamin C formulas - each expertly designed to serve the specific needs of different skin types, concerns and routines. So which vitamin C is the one for you? Read on to find out…

Will vitamin C irritate my skin?

Not with our expertly stabilised vitamin C formulas which ensure maximum power without the irritation that’s commonly associated with vitamin C use. However, if you do have particularly sensitive skin or are new to vitamin C, we recommended C-Tetra or Daily Radiance Vitamin C as the ideal introduction to this exceptional skincare ingredient. 

When should I use vitamin C?

You should use vitamin C every morning after cleansing and following application of direct acids/toners or water-based serums. For maximum skin health and age-defying results, use as part of our CSA Philosophy: vitamin C plus sunscreen by day, vitamin A by night. 

Will vitamin C help to smooth the look of my fine lines?

Yes, but our expert-led formulas will do so much more! Because Medik8’s vitamin C products are stabilised, they ensure preserved potency and therefore maximum power for visibly brightening the skin tone, reducing the look of hyperpigmentation and providing essential antioxidant protection against the ageing effects of external stressors. 

Why should I use a Medik8 vitamin C formula?

All Medik8 vitamin C products retain the highest level of formula stability, meaning that they boast preserved potency which ensures maximum visible results until the very last drop. Our carefully-curated textures also deliver an enjoyable sensorial experience, meaning that you get optimal results without having to compromise on experience.
