Please advise what is a good home remedy to brighten skin?

Neat and clean with. a pleasant disposition is the way to go. That will bring more light to our world than a lighter face. Please don't measure your self-worth by skin color. One day your opinion may reverse and you may want to darken your face. I respect the fact that you are a young and healthy and want to look attractive but who you are and what you do is the real attraction. Peace and good health.
