How does the sun affect your skin?

Vitamin D.
You probably have heard of the importance of sunlight. Our skin uses sunlight to help produce vitamin D. However, its ultraviolet light can be very harmful.
Melanin, the skin's outer layer cells, protects skin from the sun's UV rays. Within too much exposure to UV rays, melanin could reduce its elasticity and prematurely age your skin; also can damage or even skill skin cells. For those who sunburn easily should protect themselves by wearing sunblock, limiting their time of sun exposure.
The more UV rays over time may cause you to have skin cancer. Make sure to protect your skin before going out, especially when doing outdoor activities. Early detection and treatment are the keys to avoid having skin cancer.
