1. Sunscreen: This is the most basic and important whitening method. Ultraviolet light is the main cause of melanin production in the skin, so it is necessary to do a good job of sun protection and avoid exposure to the sun for a long time.

2. Hydrate and moisturize: Keeping skin moist is the key to whitening. You can choose products containing moisturizing ingredients such as hyaluronic acid and glycerin, and make masks regularly to keep your skin moist.

3. Balanced diet: Eating more foods rich in vitamins C and E, such as citrus fruits and nuts, helps to resist oxidation and prevent melanin production. At the same time, avoid eating too much greasy food and sugar, which will lead to dull skin.

4. Adequate sleep: Adequate sleep can help skin repair, promote metabolism and make skin healthier.

5. Use whitening products: There are many whitening products on the market, such as whitening essence and whitening mask. You can choose the right product according to your skin type. However, it should be noted that whitening products can not replace sun protection, nor can they see the effect immediately, and they need to be used for a long time.

6. Exfoliation: Regular exfoliation helps to remove dead skin cells on the skin surface, promote the formation of new cells, and make the skin smoother and more delicate.

7. Drink plenty of water: water can help eliminate toxins in the body, keep healthy and be good for skin health.

8. Don't stay up late: Staying up late will lead to dull skin and affect skin metabolism, so be sure to get enough sleep.

9. Exercise: Moderate exercise can promote blood circulation, improve metabolism and make skin more shiny.

10. Keep a good attitude: too much pressure will also affect the state of the skin, so learn to adjust your emotions and keep a good attitude.
