Hydroquinone is often prescribed to help lighten dark spots, but it can be irritating, potentially worsening the pigmentation you are trying to lighten. Besides that, it can only be used for three to five months at most and the effects can plateau. These options offer an alternative if you want to get spot-free without prescription-strength products.
