Hello, I will try to be as detailed as possible. I am a 23-year old male at 200lb and about 5 foot 7 inches. I do not take any medicine, have any allergies, or on any medication. I have these cuts, scars, whatever that do not seem to heal away after quite a long time under my armpits. It does not give me any pain but it is unattractive to have or look at. I want to know how I can get rid of it. Here are some photos (not really gory, just some cuts, no blood)
