Hey, there! So basically, I was once suffered from acne for years. As you know, it's really frustrating to have that kind of condition because it can really give ugliness not only to your physical appearance but to the whole of your personality aspects as well. Because of that, I became desperate to search online what are the possible remedy for it. Then, I heard a lot of positive reviews about this "Apple Cider Vinegar (with the mother)" product as acne solution. So, I bought one bottle online and follow the instructions on how to effectively use it (it's to simply put the same amount of water as with the vinegar and apply it to your face with a cotton every night and every after taking a bath in the morning). I, then, excitedly use it with so much hope that this could be the answer to my prayer. After two weeks of using it, I started to notice some blackheads and whiteheads appearing on my nose and forehead. I didn't get easily discouraged about it and I just thought that this maybe the first reaction of my skin then will just disappear soon. So, I continued using it for a month and a half, but the blackheads and whiteheads just got worse and so my acne. So, I decided to stop using it because I couldn't see its effectiveness. After two weeks of not using it anymore, those black and whiteheads completely gone though the acne is still there but it's better than it was. I'm not saying that the product has no good effect at all but maybe it's just not for me and doesn't fit on my skin type. To some people, it gives a positive effect but not to all maybe because it really depends on how your skin reacts.
