Potent Vitamin C is clinically proven to have anti-ageing benefits. CE-Thione helps protect the skin against free radicals, while minimising the formation of dark spots for a visibly brighter skin tone and improved texture and firmness.

The pH of the solution is optimised for reduced irritation while keeping the formula highly active and allowing effective penetration. Suitable for all skin types but redness prone.
