Nice underarm skin

[WelcomeHere]

Do you have this? How? Mine is literally grey.

I think I do. Not really studied it except for when I am shaving but it's not grey.

Exfoliate with a cotton pad and glycolic acid, remember to moisturise them and switch to roll on deodorants if not using already.

As in pits? Mine looks the same as the rest of my skin

I laser the hair after shaving. But even prior, always seemed ok?

Is it pigmentation?

It can be a sign of various underlying health conditions including thyroid issues and poly cystic ovaries syndrome. So if you treat the underlying condition it should improve or stop completely. Or it could be a dermatological condition, and without knowing which one the treatment could make it worse not better.
