Monobenzone topical (for the skin) is a depigmenting agent. It works by increasing the amount of skin pigment molecules (melanin) eliminated from skin cells in the body.
Monobenzone is used to permanently depigment (lighten) skin in people with a condition called vitiligo. Depigmenting (lightening) darker skin around areas of skin affected by vitiligo helps even out the coloring and appearance of the skin.
Monobenzone is not for treating freckles, café-au-lait spots, sun damage, melanoma, jaundice, or other pigmentation disorders not caused by vitiligo.
