Medik8

Medik8 is a mid-market skincare brand that creators turn to for serious, well-formulated actives — particularly their retinal and growth factor serums. The Crystal Retinal line offers a progressive strength ladder that makes it easier to build tolerance, though it can get pricey at higher strengths. The brand also has a strong growth factor serum, Liquid Peptides Advanced MP, that multiple creators rely on consistently. Overall, Medik8 delivers effective, results-driven products that tend to be worth the investment, but the pricing on some items may be a consideration.
