Some scholars said that in the past few years, people’s skin health should be copper, because the sun’s ultraviolet rays are nutritious.
This view has been greatly overturned. The radiation in the sun’s ultraviolet rays will affect the health of the skin and destroy the nutrients. If the skin absorbs vitamin C and vitamin E, it will turn white, that is, the skin with more nutrition will be whiter. In addition, staying up late or getting sick, lack of water and other reasons can cause the skin to darken, so the healthiest skin should be red and white.
