Melasma is a common skin condition that causes dark, discolored patches on the face, usually on the cheeks, forehead, nose, and upper lip. It is triggered by hormonal changes, sun exposure, and heat, making it especially common in pregnant women or those using hormonal contraceptives. While melasma is not harmful, it can be stubborn and difficult to fade without targeted treatments. Effective skincare and professional treatments can help restore a more even, radiant complexion.
