You may have had a bad reaction since you were drinking a lot of it and putting it on your face. ACV is very good for you and very antibacterial so it was probably detoxing and cleansing you at such a fast pace your body couldn't handle it and your skin got worse. It was probably a die-off reaction. I have drank it also but only 2 tbsps in a glass of water on an empty stomach once a day. I also only put it on my fact one or two times a day.
I have been using ACV for several months and it has not made my skin worse at all, although it has not cured me either. Glad the BP worked for you.
