    Can i use 2% salicylic acid and 10% active lactic acid at ph 3.8-4 in same product for daily use leave on Product on face? 

    My skin is completely ok to use 10% lactic acid once a day and 2% salicylic acid twice a day. As i haven’t seen any product with both of them i am wondered if i can mix them.

    @Abdullah Check regulations in your jurisdiction where you are selling the product. In North America, no restriction on mixing  them  and the pH has to be greater than 3.5. In fact, Deciem’s Ordinary uses Salicylic Acid and Citric acid combination
