What are the 5 methods to improve dull and yellowish skin?

Five methods to improve dull, yellowish skin mainly include: 1. Exfoliate regularly—oily skin is recommended to exfoliate once a week, combination skin every two weeks, and dry skin once every half month. This helps remove dead skin cells and brighten the complexion. 2. Maintain a balanced diet by consuming more foods rich in vitamin C and vitamin E, such as citrus fruits and leafy green vegetables, which help inhibit melanin production. 3. Ensure sufficient sleep daily and avoid staying up late, which helps regulate endocrine balance and thereby improves dull, yellowish skin. 4. Protect your skin from sun exposure in outdoor environments with strong UV radiation to minimize UV damage and prevent pigmentation. 5. Choose skincare products suitable for your skin type, use them consistently, and perform regular deep cleansing and hydration, all of which contribute to improving dull, yellowish skin.
