Why Dr Sarwar chose Medik8 for Skin65

Dr Sarwar chose Medik8 for Skin65 because it makes advanced active skincare understandable, progressive and highly usable. The brand's CSA Philosophy - vitamin C and sunscreen in the morning, vitamin A at night - gives patients a simple, evidence-informed structure for brighter, better-protected and smoother-looking skin. Medik8 is especially known for its vitamin A expertise, including Crystal Retinal, which uses retinaldehyde in six progressive strengths so routines can be tailored from sensitive or beginner skin through to experienced vitamin A users. This makes Medik8 a strong choice where consistency, tolerance and visible ageing support are central.
