I"m probably a 4 for my face, but a 2 or 3 for the rest, BUT I rarely spend much time in the sun, unless it's at Disney, or similar. I"m a hermit, and do very little outdoor activities. The few beach trips we've done, I've lathered myself in thick cream....sprays didn't help much.
I still should do better. My mom had skin cancer. always a few spots burned/frozen off at her yearly appts, and surgeries to remove cancers on her face, like nose, ear, several cheek, then needed reconstructive and skin grafts, I've mostly chosen to look like a ghost, but I made many mistakes as a teen, suntanning, not wearing sunscreen, etc.
In my mid 50s now, and have already had 2 spots biopsied/removed on my back, and now, another spot biopsied/removed , and 3 frozen off....I"m supposed to keep eye on the last removal, and recheck in 6 months..
I foresee a lot of dermatology visits like that in my future.
