About Medik8

Medik8 is a British skincare brand founded in 2009 by scientist Elliot Isaacs, with a focus on combining dermatological research, high-performance ingredients and advanced formulation technology. The brand develops clinically researched skincare designed to deliver visible results, with products spanning vitamin A, vitamin C, sunscreen, peptides, cleansers, moisturisers, serums and targeted skincare for specific concerns.

What is Medik8 known for?

Medik8 is particularly known for its expertise in vitamin A skincare and its Crystal Retinal range, an award-winning retinal night serum available in progressive strengths. The brand also has a strong focus on vitamin C, daily sunscreen and peptide-based skincare, with popular formulas including C-Tetra, Advanced Day Ultimate Protect and Liquid Peptides.

What is the Medik8 CSA Philosophy?

The Medik8 CSA Philosophy is the brand’s approach to building a simple, effective skincare routine around three core steps: vitamin C and sunscreen in the morning, followed by vitamin A at night. CSA stands for vitamin C, sunscreen and vitamin A, reflecting Medik8’s belief that these ingredients form the foundation of an effective approach to visible signs of skin ageing.

Medik8 science and formulation

Medik8 develops and manufactures virtually all of its products at its own ISO-certified Innovation Centre just outside London. The brand combines in-house research with patented formulation technologies and carefully selected ingredients, with a particular focus on the stability and delivery of active ingredients such as retinal and vitamin C. Medik8 is also B Corp certified, reflecting its wider focus on responsible business practices alongside product performance.
