I Need Some Input on my Skin Condition? (photo)

I started using salicylic acid peel 20% two months ago and this was the result. I ruined my skin, I was out in the sun a lot with little sun protection and I can't stop picking at my skin, most of the blemishes are hyperpigmentation, flat dark spots and tons of discoloration and shallow scarring. I went to a dermatologist two days ago and prescribed me doxycyline, retin a, and 5% benzoyl peroxide the alternative was accutane. I am 24 years of age btw. Any chance of improving my skin?
