Acne on chest? (Kinda TMI sorry)

Nicole • I'm a nonbinary girlflux lesbian, and 16 :)

So I'm not gonna put a pic or anything, but I have either acne or blackheads on my chest in between and under my (tiny and horrible excuse of ) breasts and a bit on my back. Yes, I shower everyday, and I wash my hair 3 times a week (so I dont strip it of all the oil ((might sound gross but yeah)) and I always wear clean clothes) I'm fourteen, so I don't know if this is part of puberty, but I've had the blackheads since I grew (prolly TMI but ok) pubic hair and my breasts started to develop. Sorry, I'm shy about this sort of thing. Thank you!
