I have very shitty skin, like shitty shitty, I'm 19 but I look 30. My hair is also falling off. I have Acanthosis Niagricans all over my neck and arms, I don't know what to do? Scrubbing doesn't help, once I scrubbed the Acanthosis part so hard it started bleeding, I used to think it was dirt.

I'm a bit dark skinned, but uneven as fuck. Like my skin is black on some spots and wheatish on some parts, makes me look ugly as shit.

Where do I start? Any skin routine help? Anyone with similar skin as mine?
