Microdermabrasion or Chemical peel for non-inflamed acne

I've been off accutane since may/08, and unfortunately my skin has progressively gotten worse. After going to several different dermatologists over the years, i finally went to a doctor that performs numerous skin treatments.

He told me i could basically choose any treatment i wanted but i'm not to sure what is best for my NON-INFLAMED acne. Anyone have microdermabrasion, chemical peels, or blue light treatment done for their non-inflamed acne? Any suggestions?

does benzoyl peroxide stunt facial hair growth?

I'm almost 21 years old and have been using dan's products for about 3 years. Since i've gotten off accutane about a year ago, my acne has steadily come back. One thing i've noticed is that i can't seem to grow any facial hair. It just seems odd to me that even though i have thick chest hair, my face has nothing. I started to wonder if BP was the cause of this b/c i apply it so heavily everyday on my cheeks and jawline. Do any of you guys have the same prob?
