A combination of natural components within your skin (including urea, proteins, 15 different amino acids and lactic acid) that bind together and lock-in moisture for deeply hydrated, moisturised skin.
Ceramides
Naturally found in the skin, ceramides work by mimicking the natural lipid barrier to deeply nourish and replenish the complexion.

A near skin-identical lipid that helps to support the skin’s natural barrier for a nourished complexion.

Perfection
[This review was collected as part of a promotion.] I have about 20ish + products from Medik8. Since using their products my skin is perfection. I used to suffer from psoriasis flare ups on my face but now my skin never has this issue. My skin is always glowing. I’d never use anything else. Thank you

Love the Products, Terrible Packaging
[This review was collected as part of a promotion.] I love the serums and moisturisers, and my entire morning and evening skincare routine consists of Medik8 products. However, the packaging is incredibly frustrating and results in so much product being wasted.
With several of the pump-style products, I find that a significant amount is still left inside when the pump stops dispensing. I end up cutting the tube open to access the remaining product, and there is often enough left for another two weeks or so. Unfortunately, once the packaging has been cut open, the product starts to dry out within a couple of days.
I’ve noticed this particularly with the day eye cream and the SPF day moisturiser. Given how expensive these products are, it’s really disappointing to have so much perfectly usable product trapped inside the packaging and ultimately go to waste.
I genuinely love the products themselves, but I really hope Medik8 will reconsider the packaging, as a more effective design would make a huge difference.

The reliable duo
[This review was collected as part of a promotion.] This mask gives results every time! I wake up with hydrated, glowing skin which is a god send with the weather change. It’s a lovely treat a couple nights a week and I love there’s no faff with a sheet mask or rinse off
