hello carlos. i am 15 as well and suffer from acne. my doctor also prescribed benzaclin which i refuse to use. know why? benzaclin may work while you use it now, but once you stop using, the Acne will flare up like a prairie fire and you will only end up buying more prescriptions and your problem will only turn into an expensive dependence... not to mention that benzoyl peroxide (the active ingredient in benzaclin) rapidly dries out skin to remove pimples. try attacking toxins at their source. if you dont have time for a colon and/or master cleanse you could try oil pulling (search forums) which is a 20 minute daily routine in which one swishes oil in the mouth to remove toxins from the bloodstream. an even faster method that does not use synthetic chemicals like benzoyl peroxide or cetaphil is calcium Bentonite clay. this is a clay used by the aztec people for centuries and is known as a miracle healing substance. i got mine at the whole foods store and applied a mask to my face just last night and am already seeing Acne disappear!
