Sun exposure can cause dark patches and uneven skin tone. It prevents damage to the skin that can occur for many years. Darker tones don’t burn as easily, which often leads to the belief that you don’t really need to wear sunscreen all the time. While Rich Complexions have the benefit of more melanin, which helps protect the skin from some environmental damage, this does not make you immune to all of the damaging effects of the sun. The built-in sun protection provided by the melanin in your skin is definitely not enough. You should always protect your skin from sun damage by routinely using sunscreen.
