I was using 15% lactic acid lotion. I think the strength was ok. It didn't sting (well, it did sting when applied to my stomach and chest sometimes, but ironically that 's not where I got the PIH). I got the PIH on my ankles and upper thighs. I think my skin just didn't agree with it. And I didn't enjoy the process either. Seeing more results with dry brushing which is odd, but I guess whatever works.
If I layered the KA serum I would need quite a bit right? (Since I'm going to be using caro white on my entire body). I would probably need like 3 bottles of KA serum each week. Is it not as effective to add it to my caro white?
Also, do you know if paks sell the legit KA Maxi White? I just realized that they have it, but I don't remember if people here have had issues with paks selling fakes or not.
Thank you soo much again @gymrat .
