How to deal with closed comedones during adolescence

When closed comedones (whiteheads) first appear during puberty, the following measures can be taken: 1. **General Treatment**: Keep the affected area clean. Use neutral facial cleansers and avoid using harsh bathing products or cosmetics. Additionally, improve lifestyle habits by maintaining regular作息 (sleep patterns), avoiding late nights, reducing intake of high-sugar, high-oil, high-fat, and spicy or irritating foods, and eating more fresh vegetables and fruits. 2. **Medication**: If symptoms are mild, topical medications such as tretinoin cream or adapalene gel can be applied to help soften, dissolve, and expel the comedones. If infection is present, topical antibiotics such as mupirocin ointment may be used. For severe cases, oral medications such as doxycycline or minocycline may be prescribed, but these should be used under the guidance of a physician. 3. **Physical Therapy**: For closed comedones, physical treatments such as red and blue light therapy or photodynamic therapy can be used to accelerate comedone maturation, reduce inflammation, and promote skin lesion recovery. 4. **Avoid Squeezing**: Do not excessively squeeze the comedone areas with your hands, as this may cause inflammation or leave scars.
