I take 2 (sometimes 3) showers a day, so I’m a pretty clean guy, but lately I’ve been noticing some (for lack of a better word) “granules” on top of my skin befor I get into the shower. Is my body sloughing off skin that fast, or is it something more serious, maybe?
Thanks and sorry if that was TMI. 
Q
Maybe you’re taking too many showers and your skin is drying out?
Was it yellow? Maybe it was pine tree pollen 
Haven’t rubbed up against a pine tree for a good scratch in ages, NinetyWt! Thanks for the “word-picture”!

Are you doing a lot of sweating?
After I do heavy exercise and sweat a lot, I’ll notice salt residue.
Just a wild guess…
