1, you must learn to sleep. You may scoff-you have to study when you sleep, but you ignore the late-night maintenance. It is easy to make your skin age = actual age x 1.2. This is why the beauty industry has pushed the concept of "time-sharing maintenance and late-night beauty" as never before. Effective sleep keeps you up for more than 8 hours every day!

2. Do a good job in sun protection. Sun protection is the basis of whitening. If you don't do a good job of sun protection, whitening is bullshit. When we go to places with strong sunshine, we must wear sunscreen, sunglasses or hats, so as to ensure that our skin is not damaged by ultraviolet rays.

3. Use isolation. Friends who usually work in front of the computer, it is best to use a cream to isolate the harm of computer radiation. You can also put some small office potted plants beside the computer desk to increase the oxygen content of the air and keep it moist.

4. Drink more milk. Drinking more milk can really make you whiter and whiter, provided that you do a good job of sun protection and don't stay up late. If you can't even do the basic work of staying up late and sun protection, any fairy medicine will be useless.
