Sudden temperature changes, excessive sun exposure, and inflammations like acne make the skin's pH alkaline. This light and evanescent cream rebalances the skin by restoring its pH to the correct physiological values (5-5.5). The use of this cream hydrates and protects, as well as freeing pores from impurities and restoring the natural hydrolipidic film. Excellent as a make-up base, day after day, it makes the complexion brighter and the skin more even, soft and smooth.
