How dark spot creams lighten just the dark spots on your skin without lightening the entire area relatively?


Most products I see aimed at eliminating dark spots on your skin are creams that are applied to the entire face, not just applied directly to the spot you’re trying to lighten. If this is the case, wouldn’t it just make your entire face lighter, and the dark spots will still relatively exist? If not, how does it recognize which part of your skin needs lightening?

Dark spots on skin are from a pigment called melanin, particularly eumelanin. These creams are most likely active on this chemical that our body makes in particular, and not just acting on all skin.
