What to do about oily skin and excess sebum production

To address oiliness in oily skin, it is recommended to keep the skin clean by choosing oil-controlling yet gentle facial cleansers; pay attention to diet by reducing intake of greasy and spicy foods; avoid prolonged exposure to high temperature and humid environments; use oil-control skincare products, but avoid over-cleansing or using harsh, irritating products. If excessive oil secretion is severe, consult a doctor to rule out potential underlying medical conditions.
