Pay attention to sun protection, eat more fruits and vegetables and drink more water, and don't rely on cosmetics. Eleven years old, the skin is still too young. I have a friend who wants to whiten early. As a result, his skin is very white but thin, and it is particularly red when exposed to the sun, and it is easy to grow freckles. It is suggested that all aspects should be fully developed after adulthood, so as not to lose more than gain.
