I used the salicylic acid pads every night after the cleanser, for anti aging purposes and it makes my skin clear and bright and beautiful and im 70 years young without wrinkles. Before i retired i was an esthetician for 17 years and recommended this product for anti aging and acne. They work for both. You can use it every night, its only 2% salicylic. I highly recommend it. 
I’ve been using this product for 2yrs now. It really helps heal a breakout fast, overnight. This batch they sent me has a strong odor and reddens my skin. Usually this product is very skin friendly. I highly recommend this product. Just not this batch. Bought Feb 1 2019.
