I have very light skin. I have burned myself twice, with blisters and real pain, with the sun. Both times were accidental. I was a senior in high school, and the seniors made a trip to Galveston, Texas, to the beach and stayed in a hotel that night. It was a cloudy day, no sun shining through, so I thought nothing about being on the beach all that day. At nighttime, in the hotel, my skin over my whole body starting hurting, I felt like I was burning up, I was hot; think I must have had fever. My whole body became one big blister over my whole body. When that happened, from then on, I never got in the sun to get a "tan". I should have been taken to a doctor, but in those days, 1951, one didn't go to a doctor unless you were one step from death.
Many years after that, my husband and I had a houseboat. One day we got into the water and I floated on a blow up thingy one person raft. I had put on sunscreen before getting in the water. Well, the water flowed over the raft and washed away the sunscreen - I did not know that was happening. After we got out of the water, my legs started burning and turning red. I had blisters up and down both legs - they were burning and I felt feverish. I could not put any material on my legs, could not touch them with anything or they would hurt like hell. I stayed mostly in bed for two days after that.
I have never stayed a period of time in the sun since that time. About a month ago, had to go to a dermatologist due to dryness on my hands. She examined my skin and said it showed I did not stay in the sun as my skin is not damaged from sun.
I see middle aged, older, women golfers and their skin looks like tanned leather. They are subject to skin cancer.
