Acne medically becomes acne, forehead acne can apply adapalene gel, benzoyl peroxide gel, azelaic acid and other ointments. The cause of acne is mainly related to the exuberant secretion of androgens, the inflammatory reaction of Propionibacterium acnes, excessive secretion of sebaceous glands, and abnormal keratinization of the follicular opening. Patients with forehead acne can use topical adapalene gel, tazarotene and other retinoids as prescribed by the doctor, which have the effect of dissolving acne. Benzoyl peroxide gel can also be applied, which can kill Propionibacterium acnes. For patients with moderate to severe acne, oral medications such as isotretinoin are recommended to promote recovery from the disease.

There are many ointments that can be applied to forehead acne, and it is recommended that patients follow the doctor’s instructions to use medication, not self-medication.
