What should I do about dull and lackluster skin?

Apply sunscreen properly during daily outings to reduce UV damage to the skin and prevent hyperpigmentation. Maintain sufficient sleep and avoid staying up late, which helps restore skin's natural glow. Consume more foods rich in vitamins C and E, such as fresh fruits and vegetables, to support antioxidant defense and skin whitening. Increase physical activity to promote blood circulation, assist in skin detoxification, and improve dullness. Use suitable moisturizing products to provide adequate hydration and keep the skin smooth and well-hydrated.
