Letter: Sunscreen protects skin from harmful UV rays

With the summer months approaching, many individuals should be reminded of the importance sunscreen plays in protecting the skin from harmful UV rays. Sunscreen blocks these rays, greatly decreasing the likelihood of developing sunburns, premature aging, and even skin cancer. 

Premature aging is the breakdown of collagen, a main protein structure in the skin, which often leads to sagging and wrinkles. Skin cancer is the most common form of cancer in the US; however, by applying sunscreen everyday, the risk of contracting skin cancer is cut in half.

While it is also important for individuals to wear sunscreen in the cooler months, the UV rays are strongest during the summertime, therefore more precautions should be taken to prevent skin damage.  There are two types of UV rays: UVA rays and UVB rays. 

UVA rays permeate deep into the skin, while UVB rays only affect the top layer of the epidermis. Generally, dermatologists recommend broad spectrum-which protects against both UVA and UVB rays- sunscreen with a SPF of 30 or higher.
