Detailed answer

While dark spots on the skin can have various causes, they can sometimes be a sign of poor liver function. The liver plays a crucial role in detoxification, and if it is not functioning optimally, it can lead to a buildup of toxins in the body. This buildup can manifest as dark spots on the skin. However, it is important to note that dark spots can also be caused by other factors, such as excessive sun exposure, hormonal changes, or skin conditions like melasma. Therefore, it is advisable to consult with a healthcare professional to determine the underlying cause of the dark spots and address any potential liver issues.
