The Medik8 CSA Philosophy® is a simple, science-backed skincare routine:

C = Vitamin C (Morning)

Use a Vitamin C serum in the morning to visibly brighten skin, boost collagen, and protect against environmental damage and free radicals.

S = Sunscreen (Morning)

Apply SPF every day to shield your skin from UV rays, prevent premature ageing, and protect against sun damage.

A = Vitamin A (Night)

Use a Vitamin A product (Retinol/Retinal) at night to visibly reduce fine lines, smooth texture, boost cell turnover, and promote skin renewal while you sleep.

Vitamin C Serums: These brightening formulas help boost collagen production, provide daily antioxidant protection, and fight free radical damage. Notable products include C-Tetra and C-Tetra Luxe for radiant, even-toned skin.

Vitamin A (Retinol/Retinal) Products: Crystal Retinal is Medik8's most iconic Vitamin A serum, offering age-defying results for reducing fine lines and wrinkles. The range includes stabilised Retinoids in various strengths for different experience levels and skin sensitivities.

Sunscreen: Next-generation sunscreens that protect against UV damage, blue light, infrared, and air pollution while preventing premature aging with lightweight, moisturising formulas.

Peptide Serums: Liquid Peptides features Growth Factor MiniProteins™ and multiple peptides for visible wrinkle reduction and skin strengthening.

Niacinamide Serums: The new Niacinamide Peptides serum visibly refines pores, clarifies skin, and improves skin texture with consistent use.

Hydration Serums: Hydr8 B5 Intense contains Hyaluronic Acid, Glycerin, and Amino Acids for deep hydration at multiple skin layers.

Cleansers, Toners & Exfoliators: Including Press & Clear (BHA exfoliating acid), Clarifying Foam, and Press & Glow for addressing congestion, enlarged pores, and texture.

Moisturisers: Options like Advanced Day Ultimate Protect and Advanced Night Restore, plus specialised formulas like Total Moisture Daily Facial Cream with barrier-strengthening probiotics and ceramides.

All products are formulated with non-comedogenic ingredients, made in the UK, and clinically tested.
