Detailed answer

Night creams are primarily designed to provide hydration and nourishment to the skin while you sleep. While some night creams may contain ingredients such as vitamin C or retinol that can help improve the appearance of sun spots, they are generally intended for use on the face. The hands are often exposed to more sun and environmental damage, and may require more targeted treatments. It is recommended to use hand creams or serums that specifically target sun spots and incorporate ingredients like hydroquinone, kojic acid, or alpha hydroxy acids. Additionally, applying sunscreen during the day and wearing protective clothing can also help prevent further sun damage on hands.
