Medik8

Medik8 is a British skincare brand built on the CSA philosophy — Vitamin C in the morning, SPF always, and Vitamin A at night. Their Crystal Retinal range uses retinaldehyde, the direct precursor to retinoic acid, which works up to 11x faster than retinol with significantly less irritation. Winner of 45+ global awards and trusted by dermatologists worldwide, Medik8 represents some of the most rigorously formulated science-first skincare available. 100% vegan.
