The PURIFYING SERUM is formulated for the intensive correction of skin breakouts. It combines a multi-acid complex containing salix alba, glycolic, shikimic, and mandelic acids. The synergistic actions of the multi-acid complex effectively eliminate skin imperfections and accelerate their resorption. This non-greasy serum regulates sebum secretion, normalizes the keratinization, and prevents the accumulation of dead skin cells. The SÉRUM PURIFIANTE also soothes irritations and reduces redness associated with skin breakouts.
