Pimples are medically known as “acne”. The main treatments for acne in adolescent boys include general treatment, medication, and physical therapy. 1. General treatment: patients need to pay attention to diet (eat less high sugar, dairy products, more fresh fruits and vegetables, etc.), develop good habits (avoid staying up late, irregular life, etc.), choose the right skin cleansing products (to avoid clogging of pores), and carry out healthy psychological counseling to avoid prolonged mental stress. 2. Medication: Mild acne patients can be treated with topical medication; moderate to severe acne patients need to take oral medication in addition to the above methods. Common topical medications include retinoids (preferred for mild to moderate acne, which can regulate stratum corneum cell differentiation, improve hyperkeratosis of sebaceous ducts, etc., and are often used in combination with anti-inflammatory and antibacterial medications), nonanedioic acid-containing drugs or benzoyl peroxide (to kill Propionibacterium acnes and dissolve acne), and antibiotics (erythromycin ointment, etc.). Common oral medications include antibiotics (doxycycline, etc., for patients with moderate to severe acne), isotretinoin (to reduce oil secretion, inhibit abnormal keratinization and the formation of blackheads and pimples), and hormonal drugs (anti-androgenic drugs, glucocorticoids, etc., which should be used in strict accordance with the doctor’s instructions). 3. Physical therapy: For mild and moderate lesions, red and blue light can be used in combination to destroy Propionibacterium acnes and reduce inflammation through photodynamic effect. For scarring acne, patients can choose laser therapy. It is recommended that patients with severe acne consult a doctor in time, under the guidance of the doctor, combined with their own conditions, to receive targeted treatment. All of the above medications should be used in strict accordance with the doctor’s instructions, do not self-medicate to avoid serious adverse reactions.
