I have to say, I wasn't expecting this to work very well, but with 0.5%salicylic acid acne treatment, I am pleasantly surprised. I have stubborn acne on my back that always feels itchy, rough, and bumpy, but it hasn't even been one week, and my back is looking and feeling smooth. There's still some blotchiness that hasn't gone away, but I am pretty satisfied! The itching has stopped, and my skin doesn’t feel rough and dry. When I see any indication of acne on my back or arms, I apply this nice citrus scented spray thoroughly, maybe twice a day all over my back in 2-3 days everything clears up. Let it dry on your skin before putting clothes on. I prefer to do it as I’m getting ready so I can walk around and let it air dry before I either go to bed or put on my outfit. I truly recommend this product for acne-prone skin.
