Who it is for

Normal to dry skin seeking enhanced vitamin C performance. Medik8 formulates it for all skin types, and the rich texture is especially comforting on dry skin.

How to use

In the morning after cleansing, massage 6 drops across the face, neck and décolletage. Leave to absorb, then follow with sunscreen. If you are new to it, patch test at least 24 hours before first use.

Why Dr Mo recommends it

A strong choice when you want greater radiance than the original C-Tetra with added nourishment.

Introduce active skincare gradually. Maintain good hydration and reduce frequency if dryness or irritation develops.
