Medik8's C Tetra Serum is formulated with an increased strength combination of two key antioxidants, this multi-function serum provides an impressive level of protection against free radicals and environmental stressors. This effective antioxidant formula also helps to brighten uneven tone at the surface while significantly stimulating collagen production within the lower layers. With daily application, this serum noticeably repairs visibly sun-damaged and ageing skin to create a more radiant and youthful-looking complexion.


Key Benefits

The new and improved Medik8 C-Tetra serum is the perfect introduction to antioxidants and their many skin benefits.

Suitable for all skin types, apply up to four drops directly onto cleansed skin and lightly massage in until completely absorbed. Use in the morning and layer underneath a moisturiser and a sunscreen for best results.

How to Use

Every morning, after cleansing, apply 3-4 drops directly to the face and smooth into the skin. Follow with a moisturiser and a sunscreen for best results.


If you are new to this product or any of its ingredients, we recommend completing a patch test first.


Please be aware that an active antioxidant serum can vary in colour from batch to batch and that most antioxidant serums will darken over time, due to the product being exposed to the air. Both of these changes in colour are normal and do not affect the efficacy of the product or its ingredients.
