What's this on my armpits, /adv/? It's not really numb

Dude that looks fucking bad whatever it is. Go see your GP ASAP

Does it feel as if there is a build up? It could be dead skin cells

That's vitiligo, loss of skincolour. Common in the armpits, hands, legs and face. I've got it on my feet, knees, armpits and hands. Not dangerous or infectious, just looks weird. Visited a doctor a while ago and treatment's useless most of the time, the only solution they offered was custom skincolour camouflage

The skin is perfectly fine, it doesn't hurt and it's not noticeably rougher. I might add that I do not particularly like sunbathing and the sun is scorching this time of the year where I live. The white on the inside is just untanned skin, or so it looks.

Oh, and my other armpit is exactly the same way.

I will go to the dermatologist on Monday, I check my skin often because my father had skin cancer.

Could be, but why the reddish rim? Will look into it.

I'd visit a doctor if I were you, I'm just speculating as it looks like mine
