Medik8 C-Tetra Advanced serum

This advanced antioxidant serum combines a powerful 20% vitamin C complex with innovative phyto-exosomes to visibly improve skin tone, enhance radiance and strengthen the skin’s natural defense against environmental damage. The formula is based on a stable form of vitamin C (tetrahexyldecyl ascorbate), a lipid-soluble derivative that penetrates the skin efficiently to stimulate collagen synthesis, reduce the appearance of fine lines and help fade pigmentation. Phyto-exosomes derived from botanical sources support cellular communication and regeneration, helping the skin repair itself more effectively while boosting overall vitality. The serum also contains nourishing antioxidants and skin-conditioning ingredients that protect against free radical damage caused by UV exposure and pollution. Its lightweight gel texture absorbs quickly without stickiness, making it ideal for layering within a daily skincare routine while delivering intense antioxidant protection and a visibly brighter, smoother complexion.

Ideal for:

• Dull and tired-looking skin
• Uneven skin tone
• Early signs of aging
• Loss of radiance
• Pigmentation and sun damage
• All skin types including sensitive skin

How to use:

Apply 4–6 drops to clean skin in the morning and gently massage into the face, neck and décolleté before moisturizer. Always follow with a broad-spectrum SPF during the day to maximize antioxidant protection and prevent new pigmentation.
