Woman applying sunscreen

No matter the time of year, it is important to protect your skin from the sun’s ultraviolet (UV) rays. The UV radiation found in sunlight and commercial tanning lamps causes damage to the DNA in skin cells, which can lead to skin cancer. UV rays from the sun can reach you by reflecting off of surfaces such as cement, snow, sand, and water. Wearing sunscreen is essential in preventing skin damage. Here is some information on the importance of sunscreen use:

When to Use Sunscreen

Apply sunscreen before going outside every day, even if it is cloudy or cool. Even in cloudy weather, UV rays can damage your skin within 15 minutes of being outdoors. The hours between 9 a.m. and 3 p.m. are the most dangerous for UV exposure. Apply a thick layer of sunscreen on any exposed skin before leaving your home, and don’t forget to cover hard-to-reach places, such as your back and shoulders.

Finding the Proper SPF

Sunscreen protects your skin by scattering, absorbing, and reflecting sunlight. When the chemicals in sunscreen interact with your skin, it protects you from UV rays. All sunscreen is assigned a sun protection factor (SPF). The SPF number tells how effectively the sunscreen can block UV rays. Many experts recommend using sunscreen with an SPF of 30 or higher.

Effective Sunscreen Application

Since sunscreen wears off, you should reapply it after being outdoors for two or more hours. You should also put more on after sweating or swimming. Before using sunscreen, check its expiration date; typically, sunscreen lasts no more than three years.
