Excuse me, how to preserve one's health to make yellowed skin white? I prefer to stay up late, and my dark circles are heavier.
Of course, the best thing is sleep, but if sleep is not guaranteed, I suggest you make a hydrating sleep mask after staying up late, usually eat more fruits and vegetables rich in VC, then eat VC and VE capsules, and usually make more masks when you are free. Drink less coffee and more milk and soy milk.
