Hii I'm 18 years old and I've been on lymecycline for about 8 weeks now and have seen no improvement, my doctor put me on them for 3 months once a day, my spots have not got better at all, I'm really disappointed!! I suffer with them the most on my cheeks and around my face, I've got 4 weeks left of them soo I'm going to see if there is any effect by then, I'm hoping
