I used as directed for about 4 mos on my arms, it helped the itching but had to stop using it as my arms were getting redder an discolored. It's been over a year since I've used it, I have very thin skin, if I hit any part on top of arms I get blood blisters, bruising, or very bad cuts,tearing the skin. Could this be a permanent damage to my arms? I've been to 2 dermatologist, MD an burn unit. I was told its ammonium lactate burns. I have had blood work checking all functions of my organs. Do you have any other info you could possibly share with me? Ty.
