Pimples on the chin area can be caused by folliculitis or herpes simplex, a viral infection. For the former, topical fusidic acid cream or mupirocin cream can be applied topically. If the inflammation still does not subside, you can take oral antibiotics, usually oral minocycline or doxycycline, etc. You can also take oral Chinese medicine, such as Niuhuang Shangqing capsule or Yiqing capsule, etc. Of course, if the herpes simplex is formed due to viral infection, topical acyclovir ointment or penciclovir ointment can be applied topically; oral antiviral drugs such as valacyclovir tablets or acyclovir tablets can also be applied topically to promote local blisters or herpes formed by vesicles and ulcers as soon as possible to collect water and repair.
