Hello, i'm priyanka, my age is 26 and i'm unmarried, I faced acne problem since teenage, I consulted a derma 4 years ago and he prescribed me benzol peroxide in night nd clindamycin in morning, and that worked well, I got a flawless skin from that, neither I got any acne after that, I used that cream since now. But from few months they r not working and I suddenly started getting acnes on my lower face, mostly on my chin and jawline. I have tried everything to get rid of it, but nothing is working, and these acnes are getting worse day by day, and they are at thr peak prior week to my periods, please help me to figure out my problem and suggest me what can I do. Thanks in advance. I have tested for thyroid and ultrasound for pcod, both were negative.
