Due to age and chronic UV exposure, human skin increasingly develops irregular pigmentation (e.g., age spots). The visible accumulation of melanin indicates a malfunctioning and/or overstimulation of the skin’s pigmentation process. Air pollution, UV light, stress, or smoking accelerate the formation of melanin by forming ROS (Reactive Oxygen Species), often called oxygen radicals. Female hormones can also trigger irregular pigmentation. Help reduce the appearance of these effects with the Professional Brightening Collagen Mask.
