What causes the Sun to make our skin brown?

Its a protection method by our body.
As the UV radiation reaches the lower levels of our skin, it tickles melanocytes, cells that basically act like photoreceptors
They detect the radiation and release Melanin, a pigment that browns our skin, making it harder for UV radiation to penetrate into the soft squishy stuff our skin is meant to protect.
