How to treat long-term recurring chin and cheek acne and closed comedones?

Long-term recurring pimples and closed comedones on the chin and cheeks may be caused by factors such as endocrine disorders, excessive sebaceous gland secretion, abnormal follicular keratinization, and Propionibacterium acnes proliferation. Additionally, diet, lifestyle habits, and mental stress can also influence acne development.

It is recommended to maintain good lifestyle habits, avoid staying up late, ensure sufficient sleep, eat a light diet rich in vegetables and fruits, and limit consumption of spicy, greasy, and sweet foods. Keep the skin clean by using gentle facial cleansers and avoid over-cleansing and excessive friction on the skin.

If acne symptoms are mild, topical treatments such as retinoic acid preparations, benzoyl peroxide gel, or antibiotic ointments may be used. For more severe acne, timely medical consultation is advised, and systematic treatments such as oral antibiotics, isotretinoin, or physical therapies including photodynamic therapy and chemical peels may be prescribed under a doctor's guidance.

Additionally, it is important to avoid squeezing pimples to prevent infection and the formation of scars.
