Q: Why does the skin turn black?
A: In order to protect against UV rays. Human skin has a cell called melanocytes, which produces melanin to help protect the skin from UV rays. Melanin comes to the surface of the skin with keratinocytes. Metabolism metabolizes these melanin and restores the original color of the skin. However, if the metabolism is slow, melanocytes cannot be metabolized normally, causing melanin to precipitate, darkening or forming the skin. Color spots.
Q: Can people who are born with very dark skin turn white after relying on the maintenance of the day after tomorrow?
A: Whitening is not to limit whitening. The skin that is truly healthy and white is natural and shiny from the grass to the surface. The degree of whiteness of the skin has its bottom line, and the skin inside the thigh is the bottom line for your whitening. Look at the inner thigh skin that the sun doesn't reach, and that's the most white level you can achieve.
Q: Doesn't it turn black when you don't expose the sun in the room?
A: Don't think that hiding in the room, the skin will not be exposed to ultraviolet rays. Long-wave ultraviolet rays will be infiltrated through the glass window. In addition, the ultraviolet light will also stimulate the skin to produce melanin, and the indoor air-conditioning environment will cause the skin to be dry and dehydrated. The dry skin is prone to fine lines and makes the face more dull.
Q: Why do Asian women are more prone to long spots?
A: Problems such as ozone hole, environmental pollution, and ultraviolet rays are more serious in Asia. The heat-immune protein in the human body is damaged by the climatic environment and reduces secretion. It cannot protect the skin normally. Melanocytes frequently secrete melanin, so Asian melanin is formed. The problem is more serious.
