I found apple cider vinegar straight scarred my center upper lip as it ate too far into skin. Removed all spots but my scar looks like a herp infection a few inches from face. Still have few large spots, and lots of tiny ones in lips, right where lips close/touch. Garlic worked some, burnt skin, peeled 2 days. Probably need to repeat 3 to 4 x to get down far enough.
