Monobenzone, marketed under the brand name Benoquin Cream, is a depigmenting agent used to treat conditions characterized by hyperpigmentation of the skin, such as vitiligo. Vitiligo is a condition where patches of skin lose their pigment, resulting in white or light-colored patches. Monobenzone works by permanently depigmenting the skin surrounding the areas affected by vitiligo, thereby making the overall skin tone more uniform. It is important to note that monobenzone should only be used under the supervision of a healthcare provider, as improper use can lead to uneven depigmentation or other skin issues.
