Problem: Over the last 2 days, many tiny bumps have appeared in a patch on my left cheek, from beside the eye to near the ear. Some are red, and 2-3 itch. There's no severe pain and no fever. The right side is mostly clear. History: I've had acne for a long time and have been treated by a dermatologist (last visit 20 July 2026). The prescription was Glazit 500 mg (a 9-tablet course, finished), Glocin gel in the morning, Peroduo on pimples in the evening, Trexoderm serum at night, Nevlon cream, and Acmed face wash. I'm still using Glocin, Peroduo and Trexoderm. I wasn't applying moisturizer until about 9 Nov. What changed recently: I popped a bump on the same cheek on 9-11 Nov. The weather has turned cold and my skin is dry and flaky. I've used cold compresses, and I've also had a few sips of cold drinks. I haven't used any new product. Question: What is this (acne, folliculitis or irritation)? Should I stop Peroduo and Glocin on that patch? Do I need a different treatment or antibiotic
