Medik8's Blemish SOS targets blemishes with rapid action. This lightweight gel utilizes salicylic acid to exfoliate and decongest pores, diminishing blemish-causing bacteria. Azelaic and dioic acids work to minimize excess oils and discoloration, while niacinamide visibly brightens and balances skin tone. It absorbs quickly, leaving an undetectable finish that can be worn under or over makeup as needed.
