I have a dark spot at my face how can I remove all of them to make face clean and fresh with glow?

That depends.If you are dark skinned any effort to remove a spot on your face may be dangerous. That's if it is what is called a freckle or sun spot.. If your spot is like a wart, or a blemish then a doctor can remove it with nitrogen gas.Otherwise it might disappear as you grow.There isn't any cream for that problem.
