A very common skin problem is Melasma. It is characterized by brown to gray patches on the face and arms. You can most commonly see this on the cheeks and bridge of the nose where the face receives the most sun. It is more common for women to get melisma, and has been called the mask of pregnancy because it can be triggered by the influx of hormones. Right now the best treatment options in lightening melisma are, hydroquinone & Alpha Arbutin. Check out this great product called Flawless Fade Cream which really does the job. It contains both Hydroquinone and Alpha Arbutin.
