Apple cider vinegar can help to improve your acne and reduce the oil on your skin's surface. By using 10% vinegar to 90% water dabbed on the face 2-3 times a day, or after washing, you should see an improvement in redness, flaking, and additional breakouts. The solution will help balance skin PH, dissolve unwanted oil, provide an antiseptic, improves scarring, and aids in the circulation that will help flush toxins from the skin.
