Inspired by the CSA philosophy, the Medik8 CSA Kit Retinal Edition brings together four targeted formulas to visibly brighten, smooth and refine the skin. This set is ideal for those ready to step up their results using next-generation vitamin A, while still remaining suitable for retinol beginners and sensitive skin types.

The kit works across the full day and night cycle. Skin is gently exfoliated and cleansed, defended from environmental stressors during the day, and renewed overnight with stabilised retinal. With proven clinical results across radiance, texture, fine lines and redness, this routine supports long-term skin health and visible anti-ageing benefits.

  • Next-generation vitamin A helps visibly smooth fine lines, refine texture and improve skin firmness.
  • Brightening vitamin C boosts radiance and defends against environmental ageing
  • Daily SPF 30 protection shields skin from UVA, UVB, blue light and pollution
  • Clinically proven CSA routine supports healthier, younger-looking skin over time
  1. Cleanse: Use Surface Radiance Cleanse morning and evening. Massage into damp skin and rinse well.
