okay so far...
I was wondering how my skin would react from this since I've been the cerave SA cleanser for a while now and didn't notice any dryness whatsoever with that. But, I've always wondered the strength or percentage of SA in the cerave (which is impossible to find out I guess...) I'm guessing it's less than 2% so I wanted to try out a cleanser with a higher % to see if there was a different. After a few days I did notice some dryness, which I suppose could be due to wintertime, but I think it's the cleanser. Not surprising, I was bracing myself for dry skin. I will probably take a break until my skin returns to normal and reintroduce this to a few times a week or something, or I may save it for the humid summers. Other than that, I like the formula, it has a very subtle scent I don't mind at all.

Smooth and oil free skin
At first I was scepticle, losing hope that anything would help my oily acne prone skin. But then I ordered this, and it's magic. Now my skin is smooth, balanced, and the acne is slowly going away. Best thing of all, no more oily skin! Will be ordering again!

BUY THIS!
I WISH i took a before and after photo of my results because the speed of which this worked was insane. Although I encourage to use the product as the package instructs you to, I just needed to share how well it worked for me and how I used it. I began applying the cleanser specifically to my acne prone areas on my face (between my eyebrows, above my lips etc) and allowing it to sit for 15-30 minutes before washing it off then moisturizing immediately after during the night time. in the morning, i cleansed those same areas once more and moisturized with spf 25 sun protection to protect my skin from dryness and repeated those steps each night for the next 3 days. 1 night i decided to just leave the cleanser on my acne prone/scarring areas and the morning after, the most stubborn scar on my face was literally GONE. it was insane. needles to say, this product worked so well for me. instantly cleared up my acne, by scarring, and stubborn bumps on my face. don’t forget to moisturize and use sun protection though because salicylic acid is in fact very drying for your skin. love this product. highly highly highly recommend.

Did the formula change?
I had ordered a travel kit of this product around christmas and it seemed to work really well. I was only really using the cleanser from the kit, and I ran out so I decided to order more. I feel like this isnt the same as what was in the kit. Ive been constantly breaking out since using this bottle. I dont know if the formula changed or what, but I can't use it anymore.
