“This product is really effective at brightening all skin types. Almost everyone can tolerate this toner and receive the amazing benefits it delivers. Expect to see tightened pores, luminous skin, and a reduction in breakouts and blackheads, giving the overall texture of your skin a really nice uniformity. I would say, to be safe, give yourself a week to adjust, just in case it purges your skin. This happens less frequently with this version of P50 than the original formula, but better safe than sorry. It smells very faint but medicinal. If you apply with damp gauze, it dilutes the smell to an almost unnoticeable level.” Biologique Recherche Lotion P50 PIGM 400
