Medik8 CSA

Medik8 Vitamin C + Sunscreen by Day,
Vitamin A by Night

Our ultimate mission is to help you achieve Beautiful Skin for Life.
How? In 2009, we invented the CSA Philosophy. Incredibly simple and grounded in science - it just works. This CSA method is becoming more and more mainstream by the day and we couldn't be happier. Just use a vitamin C plus sunscreen by day, vitamin A by night. That's it.
If you look after your skin and follow our simple advice, we believe you can look 40 when you’re 50.
VITAMIN CWell formulated, stablised vitamin C provides all-important antioxidant protection as well as stimulating collagen production and blocking the development of pigment for smoother and brighter skin. Apply vitamin C in the morning for an all-day urban shield against everyday environmental factors which can cause skin ageing.

SUNSCREENIt is estimated that 80% of skin ageing is caused by the sun. Sadly, skin damage caused by the sun doesn’t only happen when it’s sunny. If it is light out, it means the sun’s rays can still reach you. Even on a cloudy day, you will still get approximately 50% of UV reaching your skin. Wearing high-strength sun protection every day is fundamental for a youthful complexion. With its importance in mind, Medik8 have a range of beautifully light but powerful sunscreens that protect and nourish the skin. Don’t worry, our high-tech Medik8 sunscreens do not feel sticky and greasy like those used at the beach. More likely, you'll probably not even realise your sumptuous day cream contains sunscreen.

VITAMIN AAs the Experts in Vitamin A (aka retinol), Medik8 has developed a wide range of night creams and serums to rejuvenate skin while you sleep. Vitamin A is quite simply the most important ingredient in anti-ageing skincare. It has a wealth of skin benefits including speeding up cellular renewal and reducing sebum production. It is crucial that Vitamin A is stabilised and has some form of controlled-release to ensure maximum potency with minimal irritation. For more information about how vitamin A works within the skin, read our vitamin A guide. Shop for vitamin A products here.

Anti-ageing skincare doesn’t need to be complicated - in fact, it shouldn’t be. Following our simple CSA philosophy will help improve the tone and texture of your skin; leaving it healthy and youthful-looking.
