The heat of summer not only dehydrates our bodies but also dehydrates our skin, leaving it looking drab and lifeless. The UVA radiation from the sun causes the skin to tan. UVA rays penetrate the epidermis' lower layers, activating cells known as melanocytes. Melanin, the brown pigment in the skin that promotes tanning, is produced by these cells. Tanning raises the danger of skin aging prematurely. Our hands receive the most sun exposure since they are rarely shielded from the damaging rays. This may result in skin discoloration and an uneven skin tone. People may employ harsh treatments to remove tan from their hands, such as bleaching their skin, but this promotes further darkening.
