I recently went to a beach with my family and friends and I got a terrible sunburn that scabbed over and peeled terribly. I have also had a terrible sunburn before with giant blisters about two years ago, and this past weeknd I had gone to the beach, I put on sun lotion as usual but when we got back I only had a little on my nose which has now scabbed over. I m really concerned about this because I could develop skin cancer, my father has had skin cancer on his face before but he still might have it. I know I have messed up from not using sun lotion, but is there anyway I could possible prevent from getting skin cancer at this point?
