What should I do about oily skin?

1. Reduce intake of high-sugar, high-fat, and spicy foods, and increase consumption of fresh vegetables and fruits, especially those rich in vitamins, to help regulate sebum production. 2. Avoid using strongly irritating products such as alkaline soaps to prevent worsening skin oiliness. 3. Avoid staying up late and prolonged exposure to electronic screens. Increase physical activity to promote metabolism and sweating, thereby reducing sebum secretion. 4. If excessive oiliness is severe, seek timely evaluation at a dermatology clinic to rule out underlying conditions such as seborrheic dermatitis.
