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 could be dead skin on my hands: tiny balls of grey and white junk, the size of one to several sand grains, but not hard to press like sand or a tiny particle of wood.
The other thing that crossed my mind is it could be rests of the chemical sunscreen I use. Has this ever happened to you with chemical screens?
Is this normal?
Your skin is constantly shedding. The dust you can find In a house is mostly dead skin. Applying sunscreen could make it stick instead of fall off. If it’s dry it could also be dust and sand in the air.
Try scrubbing before going sunbathing to see if it still happens then.
