What should be done about a 7-year-old girl developing acne on her face?

For a 7-year-old girl experiencing acne on her face, the following measures can be taken: 1. Lifestyle adjustments: Maintain a light diet and reduce intake of high-sugar and oily foods; ensure adequate sleep, recommended 9-10 hours per night; increase time spent on outdoor activities to promote overall health. 2. Skin care: Use a mild, non-irritating facial cleanser to regularly clean the face. Avoid frequent touching and squeezing of acne to prevent infection. 3. Topical medications: If acne is severe, topical creams containing ingredients such as salicylic acid and benzocaine may be used under a doctor's guidance. These medications can help exfoliate the skin, reduce sebum production, and provide anti-inflammatory effects. 4. Medical consultation: If the above measures are ineffective or if acne continues to worsen, timely medical attention is recommended. Consult a healthcare professional for more specific diagnosis and treatment advice.
