Acne, also known as pimples, is a common chronic inflammatory skin disease of the sebaceous glands of the hair follicles. It occurs in adolescents, with acne, papules and pustules on the forehead, cheeks and chin as the main symptoms. Clinical treatment requires the active cooperation of patients and the strengthening of personal daily life management to avoid the recurrence of acne. The main treatment modalities include the following: 1. Oral medications: Oral antibiotics are preferred to tetracyclines, such as minocycline and doxycycline, followed by macrolides, such as erythromycin, etc. Oral retinoids can also be used for treatment, such as isotretinoin. Female patients can take estrogen and progestin drugs such as cyproterone acetate tablets and spironolactone as prescribed by the doctor to counteract androgens, reduce sebum secretion, and relieve acne symptoms. For fulminant or coalescing acne, oral glucocorticoids can be taken as prescribed by the doctor. 2. Topical topical medications: Local retinoids such as retinoic acid cream, adapalene gel, tazarotene gel, etc. can be used, or peroxybenzoyl gel can be applied to kill local acne propionibacterium. Antibiotic drugs such as clindamycin, erythromycin, and chloramphenicol can be used topically to fight the infection, but it is not recommended to share with retinoic acid drugs as well as benzoyl peroxide to prevent the appearance of drug-resistant bacteria. In addition, drugs such as compound sulfur lotion and azelaic acid are also effective in the treatment of acne. 3. Physical therapy: For patients who cannot tolerate or do not want to accept medication, physical therapy, such as photodynamic therapy (PDT), fruit acid therapy, laser therapy, etc., can also be considered. In daily life, patients should pay attention to diet, avoid greasy, high sugar, spicy and stimulating food, and eat more fresh fruits and vegetables. It is also necessary to maintain good work and rest habits and avoid staying up late. At the same time, ensure a comfortable mood, which is conducive to the recovery of acne.
