The larger the screen/greater the magnification, the easier the task and more accurate the results. I myself have
, tiny, 'blister-like' bubbles just under my skin
on one pinky and down the sides of two fingers. Eventually, they will flake or peel, but this typically occurs after a weekend at the beach (in the ocean) or hours in a pool. Rarely, I've had them on my right palm (I'm a female ... No self-pleasuring, hairy palm jokes please).
