1st step: Depigmentation activating essence (10% AHAs) helps diminish the color of brown spots from the very first days of use by working to eliminate surface pigment buildups & stimulate cell renewal. 2nd step: Intensive depigmenting serum (stabilized vitamin C, botanical extract of mandresy, micro-algae extract) helps regulate the production of the 2 pigments specifically involved in the appearance of brown spots, with brightening results after just 30 days. Enriched with a botanical extract of litchi, it works to prevent the reappearance of brown spots & improve skin quality.
