Why does skin color become black in winter and white in summer?

Because the weather is dry in winter and the facial skin lacks moisture, the skin color will become dull and dark.

Dry skin can be coated with some essence with good moisturizing function on the face, and then coated with some moisturizing cream for better moisturizing effect.

Of course, a good work and rest can better maintain the skin and reduce various skin problems. 8 pm to 12 pm is the best time for skin repair and renewal. When sleeping, the body almost no longer secretes neurohormones, and the skin can be relaxed and rested, so a good work and rest can bring better skin.
