Medik8, known for its science-backed approach to skincare, was founded in 2009 by a scientist. The brand focuses on its CSA philosophy – vitamin C, sunscreen, and vitamin A (retinals). Dermatologists, facialists, and celebrities like Hailey Bieber and Rosie Huntington-Whiteley are fans. The shopping editor began using Medik8 after a dermatologist recommended a vitamin A derivative for persistent acne. She saw near-instant results with the crystal retinal and now uses several products.
The brand's summer sale offers 20% off nearly all products until Saturday 1 August. Here are five recommended formulas.
