Acne help? Please, I really need help?

So I know I asked this before, but I didn't get an answer. I'm 16 years old, and swear I'm not just looking for attention or trying to ask stupid questions or anything. I'm using the "Women's Health" category because I find that women on this site are generally more serious and knowledgeable than men, especially when it comes to things like this.

As of about 3 months ago, I've been having troubles with acne. Mostly it's been on my cheeks, and simply won't go away! I mean, makeup covers it up fairly well (without using too much of course), but I'm not a huge fan of makeup, and would like if I could have a relatively clear face again, like I did before.

I'm not sure if this was caused from stress, or what, and have been using Neutrogena Acne Control for about 2 months. Does anyone know of any other products that work well, or better at clearing up acne? And will I be left with many scars? If so, is there any way to reduce them, without using surgery?

Thanks so much for all your help.
