It started last month. There is a sudden pimple breakout in my face. And the thing is, it is located only on my chin. I read articles about facial mapping and hormonal imbalance. But it doesn't help. It never happened to me before. I always wash my face after waking up and before sleeping. I dunno how did it happen. Can someone tell me what should I do to prevent this pimples on my chin? Because it really is irritating and I think it is not normal anymore. Everday theres always another one popping on my chin. Pls help. TIA
