How to recover from dull, yellowish skin caused by staying up late

Methods to recover from dull, yellowish skin caused by staying up late mainly include the following: 1. Adjust sleep schedule: First and foremost, avoid staying up late and maintain a regular, consistent sleep routine. Getting sufficient rest helps stabilize metabolism, allowing dull, yellowish skin to naturally improve. 2. Dietary adjustments: Consume more foods rich in vitamin C, such as oranges, kiwifruit, and tomatoes, as well as items like red dates and goji berries that help improve blood and vital energy. These foods are effective in improving sallow complexion. 3. Skin care: Pay attention to facial cleansing and moisturizing. Use skincare products with antioxidant properties—such as those containing vitamin C—which can help reduce skin dullness and pigmentation issues. Additionally, treatments such as photorejuvenation may also help improve dull, yellowish skin, but should be performed under the guidance of a qualified physician based on individual conditions.
