Ever heard of Live Clean? They started as a hair care brand and now have their own skincare line. LOVE IT. Excellent quality ingredients, really gentle and effective. I second the Clarisonic too, it's definitely a worthwhile investment. As far as acne, diet does play a huge role in mine (dairy and carbs KILL my skin), as well as not drinking enough water. Good old 2.5% benzoyl peroxide is all you need, though. Don't pall prey to things like Proactiv or other skincare lines that have many high % different active ingredients. They are overkill and irritate and dry out your skin more than anything.
If you want to head to the doctor and get something prescribed, Retin-A is excellent and also works for wrinkles! Many women use it with much success for both acne and aging.
Just a few things that have worked for me. :) Diet really, really does have a big impact on my skin so you may want to consider changing your eating habits and enjoying the results. Not only that, clean eating will have positive effects in all aspects of your health. Good luck! Skin is a tricky one to deal with.
