I had been struggling a lot with back acne and nothing was helping. I had tried quite a few products and my back was still breaking out pretty consistently. I was honestly dreading the summer because I didn't want to have to avoid bathing suits and dresses. I have used the 15% salicylic peel on my back a few times and I use the gly-luronic serum every time I get out of the shower and have had a huge improvement. Starting to love my skin again. Thank you!!
