Whats the best way to get rid of acne, i've tried benzoyl peroxide, and monodox, (doxycycline monohydrate) and every otc thing i can find?

Retin-A cream: A possible next step is to try a prescription cream called retin-a. It is a form of vitamin a and promotes skin turnover (less dead skin for bacteria to become trapped). A side effect is minor irritation at the beginning of use and increased sensitivity to sunlight.

Improve not remove: The best treatment is Accutane but most start with antibiotics & skin care regimen with benzoyl peroxide/salicylic. Acid many options exist for cosmetic improvement and include anti-inflammatories, peels, exfoliation, lasers, resurfacing, bleaching, excision, grafting, fillers, and much more, scars vary in their severity and so do the treatments. See plastic surgeon/dermatologist/ent for options.

It's time for...: A consultation with a good dermatologist, since you've tried all the basic steps. You will likely need prescription-level products.
