An uneven skin tone results mainly due to an excess of melanin. Melanin gives skin and hair its color and helps in protection against UV light. But overproduction of melanin stirred by extreme sun contact, hormones, or scarring, leads to a spotted, uneven skin tone. Irrespective of the causes, dealing with an uneven skin tone can be frustrating. It can be downright embarrassing going out in public when you have skin discoloration. Luckily, you do not have to be stuck with an uneven skin tone forever.
