Redness and enlarged pores on both sides of the cheeks may be due to sensitive skin, or it may be caused by seborrheic dermatitis or rosacea. The patient can be improved by medication under the guidance of the doctor. 1. Sensitive skin: Sensitive skin may be formed by repeated use of hormone-containing or irritating medications or skin care products over a long period of time. Patients are advised to choose mild skin care products and stop using hormone products. 2. Seborrheic dermatitis: Seborrheic dermatitis is usually caused by exuberant secretion of sebum and infection with Malassezia. In the treatment, you can use selenium disulfide lotion, pimecrolimus ointment and other drugs. 3. Rosacea: Rosacea is mainly characterized by persistent erythema and dilated capillaries, and can be treated with antibiotic ointments such as metronidazole or clindamycin. For patients with redness on both sides of the cheeks and large pores, it is recommended to go to a regular hospital for examination and standardized treatment under the guidance of a professional doctor.
