What is the best product, that's not too expensive, for clearing up acne

If you ask three different people this question you will get three different answers and the reason why is everybody's skin is different and work differently on everybody.  I have a 16 and an 18 year old and this is a recurring issue.  For my kids the Avon Clearskin has been the most effective.  While the Clean and Clear spot treatment helps its a consistent routine that keeps their skin clear. 
I've read lots of positive reviews on the Neutrogena System as well, but haven't personally experienced it.  All these solutions are so reasonably priced it won't break your budget. 

Zapzyt Soothing Aloe & Natural Botanicals and Patented Breakout Clearing Formula with no Irritation.Penetrates deep into pores where pimples start; for hours ofinvisible, moisturizing, oil free treatment.  This treatment smoothesinvisibly into your skin so you can even wear it under makeup!  Some says works better than Proactiv.

Cuticura soap is non drying to the skin, and works great!  You cant beat the price either.

Phisoderm treats and helps prevent acne blemishes on the body and face.

I found a great Product for you. Thou I don't know if you are suffering from Teen or Adult acne, or even how severe it is. I do recommend this product with prescription quality formulas, and Benzoyl Peroxide, Vita-C2 Clear is the affordable alternative to high priced treatments. Use Vita-C2 for all types of acne and for all teens and adults as well! Enjoy!
