Stay away from chemicals first and foremost. Wash your face with purified water and african black soap, then exfoliate with sea salt and put yogurt on your face as a moisturizer. It will clear up your acne within two weeks.
Also change your diets. Become vegan, drink lots of water and avoid dairy and your skin will be continously clear and the acn will not return.
Dan just wants your money. Don't use his products - they're poisonous to your bodies and your skin.
