So you must fight it with the right tan removal treatments. Suntan harms the immune system and can lead to further skin damage and aging. There are different types of skin tan and reactions to the sun based on your skin color. This further darkens due to oxidation and causes skin tanning. When UVA rays penetrate the layers of the skin, they signal the melanocytes (skin’s cells) to produce excess melanin (skin-darkening pigment). However, it induces damage to DNA that further boosts the production of melanin. Unlike UVA rays, UVB doesn't trigger melanocytes. Exposure to these rats surges in summer and lessens during the winter. UVB rays usually harm the upper layers of your skin. Melanocytes cells release melanin which causes the brown, dark colour of your skin. The UVA rays penetrate the deeper layers of your skin, thus damaging the cells. These rays are said to be the most dangerous element responsible for causing skin tan. The solar spectrum (sunlight) consists of UV (ultraviolet) rays at three wavelengths So the higher the UV rays exposure, the higher the pigmentation, and the darker the tan. This helps to absorb the radiation from UV rays. Your body releases melanin just under your skin’s surface when exposed to harsh sunlight. This is the body's natural way of shielding the skin from sun damage. Tanning is the process of melanin (skin pigment) increase caused by exposure to sunlight.
