S.O.S. PURIFYING SERUM (20ml)

The Biobalance S.O.S. Purifying Serum is a spot treatment for blackheads that contains a two-phase formula with activated charcoal, salicylic acid, lactic acid, and zinc oxide. It works by exfoliating deep inside pores to remove dead skin and oil, helping to prevent blackheads from forming while also controlling excess shine. It is designed for oily, combination, and blackhead-prone skin and is applied at night as a spot treatment before rinsing off in the morning.
