I use to have clear skin. Since moving to a new place, I start to have lots of acne on my face, particularly on my forehead. I thought that it would disappear soon but it has got worse. I did some research and assumed that it has caused due to drinking cow's milk. Even after stopping it, it is not getting disappeared. I notice that I have deep acne while nearing my period, along with small red bumps. I got an acne soap and I am using it for a month now. But I am not sure if it works. Please help me.
