The effective Vivier® Acne Treatment System (formerly known as SkinTx Acne Treatment System) uses Benzoyl Peroxide and Salicylic Acid to quickly and dramatically improve even significant acne breakouts. With one of the highest percentages of Benzoyl Peroxide (5%) available, patients can expect an obvious improvement to their skin. Patients who are sensitive should use Lotion once a day and Wash twice a day, whereas others may use both up to twice a day, morning and night.
