Hey,
I would say that this is mostly hormonal changes. It happened to me at the same age as well.
Eat more omega 3s, vitamins (A,B,C,D,E,K), healthy carbohydrates from veggies. And cut out the bad food. Just message me for details, feel better mate
Cheers

I agree with the above poster. Acne is absolutely normal given your age. I'm not sure if there is much that you can do except ride through out but it may help to look at your diet as a possible way to lessen the breakouts.

Hang in there hun.
