i do this too. i'll scour my face for anything, pulling hairs and acne. then my shoulders, upper arms, back, chest. or i'll sit and go over my thighs, picking out ingrown hairs, sometimes my knees and lower legs. i like to tweeze out thick hairs. sometimes i'll get going without tweezers, trying repeatedly on hairs until i get the right grip with my fingers/nails. then my fingers are sore. and i'll go at my ears, and my scalp... anything i can pick. i waste so much time doing this... but i can't stand leaving acne, i actually feel kinda satisfied when i get a pressurized splurting one. and when it's something i don't need a mirror for it's just compulsive, almost dissociative. at least i usually get myself to stop before going at something too badly that's visible to others.
