ACV can be harsh to the skin. What helps me is Bentonite clay mask and milk kefir application(I alter them). I apply them very often , every 2-3 days, seems to work.With milk kefir , I have read, you need a little bit patience: the application myust be repeated for 3 weeks. As for Bentonite clay mask: it works immediately, making flakes dead. These treatments work the best in conjunction with anti-sugar/wheat diet.
