Help getting rid of acne?

Hell, i am 16 years old and I hold had acne since i be 13, but it started getting worse from 14-16. The acne is mostly on the sides of my cheeks next to my side burns and on my arms and for a time on my back.I tried proactiv but i found out i am allergic to benzoly peroxide. I tried acne frontage wash next to Salicylic acid and spot treatment near Salicylic acid but they own not helped much. I drink 12 8 oz eyeglasses of water every hours of daylight, i don't eat greasy foods, i workout at the gym 6 days a week, wipe my face 4 times a time and shower everyday. I talked to my doctor roughly speaking my acne and she prescribed me with a oral medication call Doxycycline. I have be taking Doxycycline for 5 months and have not notice any improvement. So what am i doing wrong or is it lately my age, thats what alot of people report to me. Thanks in credit.Help getting rid of acne?
ok, that is obedient, but you should also know that if you just use products that dry out your skin, you kneed to use a moisturizer at darkness or during the day (i own very slippery skin so i usually use it at night). Otherwise, your skin will dry out, and then your body will produce more grease on your skin, clogging more pores, forcing you to use more drying products, and creating a vicious circle.
I think that you should try using oxy pad. I have be using them and they are really great. My face have stayed acne free. Good luck!
Try baking soda. I kow it sounds strange but it works unless your one of those people whos acne adapt after a while. If so it should work for a little while. It say that it helps receive your skin softer and it is also usable in child baths. The box it comes in should own a list of possible uses on it.
