Nighttime gel helps clear breakouts and reduce visible skin aging. Salicylic Acid sloughs off pore-clogging skin cells-a process that slows with age-to inhibit development of further breakouts. Tea Tree Oil soothes skin while you sleep. Contains Niacinamide, Biotin, Zinc Gluconate and Caffeine, as well as natural extracts of Meadowsweet, Yeast and Licorice.
