Apple cider vinegar is a powerhouse when it comes to acting as an acne remedy. Why? It kills off the bacteria that may be causing all the trouble in the first place. It also becomes alkaline, and balances the pH of your skin, which in turn makes it harder for bacteria to thrive. To top it off it�s an astringent, like lemon juice, and will help dry up excess oil. Keeping that in mind, don�t overdo and dry out your skin too much. This could cause the sebaceous glands overproduce to compensate, therefore triggering an outbreak.
