We describe a case of a 70-year-old woman who had been using a skin-lightening cream containing hydroquinone for a previous diagnosis of melasma. She presented a hyperpigmentation predominantly on her cheeks and eyebrows. The biopsy showed deposition of yellow-brown globules in the dermis. A diagnosis of exogenous ochronosis was made. An attempt of treatment using a Q-switched Nd:YAG laser has been initiated recently.
