Sunlight causes tan: There is a multibillion dollar industry built around this concept. Uv light increases the activity of your pigment producing cells called melanocytes. This is done to protect your skin cells and the rest of your body from uv radiation which can cause cancer. Always use sun block and do not do fake tanning.
