Acne can be effectively removed. Acne belongs to a kind of acne and can be removed through general treatment, medication, and physical therapy. 1. General treatment: Acne is mostly due to factors such as exuberant sebum secretion, abnormal keratinization of cells around hair follicles, and bacterial infections. Normally, we should pay attention to the cleanliness of the skin, use mild cleansing products to wash the face, avoid eating high sugar and greasy food, develop good habits, and keep a good mood. 2. Medication: For mild to moderate acne, topical retinoids such as retinoic acid cream and adapalene gel can be used as prescribed by the doctor; for those with obvious inflammation, benzoyl peroxide can be used as prescribed by the doctor. For moderate or severe acne with obvious infection, oral antibiotic treatment, such as doxycycline, can be prescribed. 3. Physical therapy: For those who cannot tolerate the medication, photodynamic therapy can be adopted, which utilizes photosensitizers to be absorbed by the sebaceous glands of the skin, and then irradiates the skin with specific wavelengths of light to produce a bactericidal effect, removing acne. If you have acne, it is recommended to go to the hospital in a timely manner, under the guidance of a professional physician standardized treatment, do not self-medication.
