I've been getting this some on my legs and arms and its not itchy just only redness and its not fading away for some time now and it really just not looks nice and I just really dont know what this is. Can anyone please tell me what this is and how do I get rid of it because its not really helping with my self esteem πŸ˜₯πŸ˜“
