You have come to the right place!! There are so many things you can do for acne and its all on this board if you do a little research and a little reading. I was at a loss for ideas on how to treat my acne until I came across this board and now I'm almost clear (*knock on wood*). This board is the best and the people are really helpful... brutally honest at times though, but thats what I like about them

.
It sounds like topicals dont work for you too. I had tried every damn topical under the sun with little or no results. I was also on antibiotics which did very little and got me really sick (they built up in my body and had a toxic reaction

Since your younger, you might want to try BCPs (birth contol pills)... that alone usually helps alot of girls your age. Thats what cleared up my little sister who is 16. Also I suggest an oral med called Spironolactone (or Spiro). Thats what I'm taking right now and it works great! There is tons of info on this board about it, just do a search.
Also, if your acne is severe, you could talk to your doctor about Accutane. There is also a ton of info about it here... but its a very controversial subject among the members of this board. Just mentioning it can spark a huge debate on here. It will get rid of your acne for sure (its 100% effective) but the results may or may not be permanent...sometimes acne will come back after treatment. There are alot of
potential side effects associated with it... some of which can be severe. I'm not for or against it, people have to educate themselves on the risks and benefits and make their own decisions when it comes to Accutane. If it means saving someone from disfigurement and a lifetime or torment and low self esteem, then I'm all for it because nobody should have to live like that. Anywho, that just my opinion... hope I dont get shunned for it

.
Just a few options... hope this was somewhat helpful. Good luck hun.
