1. Sun protection: No matter what the weather is, as long as it is exposed to the sun for a long time, it may cause the skin to turn black. Because sunlight contains ultraviolet rays, it is necessary to take sun protection measures, such as wearing a hat, holding an umbrella, wearing sunglasses or applying sun protection agents.

2. Healthy diet: Food has a great influence on the skin. Eating more fruits and vegetables, especially foods rich in vitamin C, such as tomatoes, strawberries and kiwis, is helpful for skin whitening. However, if you often eat foods containing many trace elements, such as shellfish, your skin will turn black easily. Therefore, the diet should be selected and prepared according to the needs.

3. Adequate sleep: The quality and quantity of sleep have a great influence on skin color. Long-term lack of sleep will lead to black eyes, but also affect health and skin condition. Therefore, ensuring adequate sleep is the key to maintaining skin health.

4. Good mood: Emotion has a great influence on the human body. When you are refreshed, your immune function is greatly improved and your ability to resist various diseases is enhanced. When the mood is bad, sad and sad, the body's immune function is reduced, the resistance is weakened, and various diseases are prone to occur, and the skin will become dull, dry and wrinkled. Therefore, maintaining a happy mood and optimistic mood is very important for the health of the skin.

5. Body exfoliation: The accumulation of old keratin will lead to rough and dull skin. For exfoliating the body skin, you can choose to use exfoliating bath essence or exfoliating products to help remove dirt and waste on the body surface and make the skin smoother and more delicate.
