I never had such bad acne and I'm not sure what triggered it, but it started to cause me to have ugly acne scars. Nothing would get rid of them. I ordered the Mandelic Acid peel, serum and TCA Peel 18%. After 4 weeks of using the combination of items (of course I don't do them all at once) haha...my skin is slowly coming back around and I'm so excited! Here's a before and after pic. As well as a photo with makeup on. Before using the peels, my makeup wouldn't even cover the scars. It was THAT bad! I'm slowly regaining my confidence, again. Thank you MUAC!
