Designed to help acne sufferers restore their acid mantle (which acts as a barrier against bacteria), Acu Mist hydrates the skin and protects against transepidermal water loss, whilst also helping to prevent acne-causing bacteria from entering the pores. Spray over skin before Acu Moist w/ SPF 15 and work into the skin together. Acu Mist can be sprayed over the face multiple times a day.
