Sophomore year of highschool wrestling + popping pimples + hormones destroyed my face with acne, been to dermatologist (robber) and tried a variety of things. In my first year of college now, it's been getting better as years passed but I recently started getting these breakouts along my jawline that are insanely itchy and a bit of acne on my cheeks again. Absolutely sick of it and want to get rid of it once and for all. Have some scabs at the end of my jaw and the skin around there and my cheeks is very dry/flakey.  The yellow powdery residue around my face is from this product I have been trying  http://www.ulta.com/ulta/browse/productDetail.jsp?productId=xlsImpprod6200691

Trying my hardest not to touch my face despite the excruciating itchiness, what type of acne is this and what should I do to kill all of this acne for good?
