This B21 program, specially created for combination to oily skin, helps to "re-educate" skin cells by enabling them to recover healthy cell functions. Astringent Purifying Lotion ideally completes the action of Purifying Balancing Gel. Alcohol-free, it tightens enlarged pores and has a purifying, refreshing effect thanks to extracts of Polyporus, used traditionally in France as a purifying elixir. The skin is visibly toned, mat and soft. Apply morning and night after Purifying Balancing Gel
