Redness and pimples on both sides of the cheeks are generally known as acne or rosacea, and can be treated with general treatment and medication as prescribed by the doctor. 1. General treatment: It is recommended that patients keep their facial skin clean and remove makeup to prevent acne from worsening due to makeup residue. 2. Medication: Patients can apply benzoyl peroxide to the affected area as prescribed by the doctor, to play an anti-inflammatory effect, improve epidermal keratinization, and promote the recovery of acne. You can also use antibiotics, such as fusidic acid cream, as prescribed by your doctor. In severe cases, oral medications can be taken under medical supervision. Acne vulgaris and rosacea are treated slightly differently, as rosacea is often accompanied by dilated facial capillaries and impaired skin barrier. It is recommended that patients with redness and acne on both sides of the cheeks seek medical attention for proper treatment.
