A dark discoloration around the mouth or lips  is a result of increased pigmentation of the skin (hyperpigmentation) which may arise for a number of reasons. This common cosmetic problem is characterized by the darkening of the skin around the mouth area, particularly at the corner of the lips,  as a result of the over activity of the melanocytes, which are the skin cells that are responsible for the production of melanin. Melanin is a natural pigment responsible for the color of our skin and provides protection against the sun. Discoloration around the mouth is more common in females and occurs more commonly in persons with a darker skin.

Skin Lighteners & Whitening of the Skin Complexion

Skin lighteners (bleaching or whitening creams) are a commonly used cosmetic product among men and women looking for a lighter skin complexion (‘fair skin’) for aesthetic purposes. Cultural misconceptions and personal beliefs about the appeal of a lighter skin complexion have made these creams, soaps and lotions a popular beauty product in Asia and Africa among darker skinned ethnic groups. A lack of appropriate regulation in many developing countries allows for these products to be sold over-the-counter although it contains pharmacologically active and toxic compounds like hydroquinones, corticosteroids and mercury.
