Girls, hi! We've had these small pimples on our face for about a month now. It's been four months and it hasn't gone away yet, all the cheeks are bumpy with a crusty coating. We went to the doctor, he said to take fenistil, we took it for a while, it started to improve, and then it came back again, we started taking fenistil again but without any results. What should I do? Can anyone tell me how they dealt with this? Please share your experiences.
