Why do I need to wear sunscreen?

Not only can the sun lead to immediate problems, such as sunburns and heatstroke, but it can also lead to long-term damage, including, wrinkles, sun-spots, and skin cancer. Damage is caused by UV rays emitted by the sun. They can be damaging even on a cloudy day or reflected off of snow. UV-B rays cause sunburn and UV-A rays can cause long-term damage such as pre-mature aging. Because of this, it is important to find a sunscreen that protects against both UV-A and UV-B rays.
