Acne on the forehead is actually a common site for acne to occur because the hair follicles and sebaceous gland openings in the forehead area are clogged, or the secretion and distribution is more vigorous and dense, which can be applied topically with ointments or creams. Usually, if the inflammation is not too obvious, you can use Adapalene gel, Daphne gel, or Clindamycin gel for topical application, or you can use some other anti-inflammatory medications. If anti-inflammatory drugs are used, it is important to clarify whether there is an inflammatory reaction. Usually, fusidic acid cream, mupirocin cream, or erythromycin cream can be used.
