How to whiten yellowish or dark skin

Methods for lightening yellowish or dark skin: 1. Dietary adjustment: Consume more foods rich in vitamin C, such as lemons, tomatoes, and kiwifruits. Vitamin C in these foods can inhibit melanin formation and help whiten the skin. Additionally, foods rich in vitamin E, such as walnuts, sesame seeds, and peanuts, have antioxidant effects that can improve yellowish or dark skin conditions. 2. Sun protection: Strict sun protection is essential to avoid ultraviolet radiation stimulating the skin. Use sunscreen, wear protective clothing, and wear hats as preventive measures. 3. Ensure adequate sleep: Maintain sufficient sleep and avoid staying up late, which helps improve dull, yellowish skin caused by endocrine disorders.
