COSMED Vitamin C30 Serum

30% Ascorbyl Tetrasopalmitate, the most stable and effective form of Vitamin C. It’s oil-soluble so it penetrates skin faster than any other form of vitamin C out there.
Because of its antioxidant properties Vitamin C aids in your skin’s natural regeneration process, which helps your body repair damaged skin cells.

Ascorbyl Tetrasopalmitate is able to reach the dermis and pairs well with other forms of Vitamin C and Retinoids for enhanced effectiveness:

Antioxidant: it destroys the free radicals that cause premature aging
Brightening: it fades away discoloration by reducing the production of melanin by more than 80%
Firming: it boosts the production of collagen (more than ascorbic acid)
Oil soluble: deeper penetration without causing breakouts
Odourless: no bad odour
Colourless: does not stain the skin
Stable: more stable than other forms of Vitamin C and can be used in higher concentrations without drawbacks
