I’ve started sunbathing because… reasons.

second day: I applied sunscreen to my skin and after some 30 seconds of rubbing my arms, I started to see what I assume is dead skin on my hands (the other thing that crossed my mind is it could be the chemical sunscreen I use, has this ever happened to you with chemical screens?).

Whatever it is, it feels a bit sticky and they look like tiny balls of grey and white junk. What is it?

Is something incredibly wrong with my skin?
