Are there ways to make my skin lighter naturally?

Sun exposure: The less sun exposure , the lighter the skin. The usual sunscreen may not be that effective in preventing tanning even if it contains a lot of zinc or titanium. Use an umbrella or wear a wide-brim hat when outdoors may help. You can get tanned even when the light is filtered by the window glass. There are chemicals to bleach the skin but they are not natural by any means.
