Difference Between UV Rays

When it comes to protecting your skin, it is important to first understand the difference between UV rays, in particular UVA vs. UVB rays, and how they impact our complexion.

When most people think of sunscreen, they think of lathering it on during a vacation at the beach or poolside. However, many don’t consider the ways UV rays can target your skin just by driving your car.

The Difference Between UVA vs. UVB

UVA and UVB rays can hit us at any time.

This is particularly true for daily routines such as driving in your car, where your left side is particularly vulnerable to these harmful rays.

In fact, studies show that the left side of the face is approximately 20 times more vulnerable to sun damage due to sun exposure while driving.

UVA rays have a longer wavelength and are commonly associated as a cause for some skin cancers.

UVB rays generally have a shorter wavelength, and while they may lead to skin cancer, studies show that UVA rays tend to be more responsible for those tendencies.

Car Windows

It may come as a surprise to learn that many cars only have the ability to block about half of UV rays.

Even the most expensive luxury cars, or those with tinted windows do not seem to protect against a significant exposure to these harmful rays.

Protecting Yourself From UV Rays

In order to limit your UV exposure while you drive, there are many precautions you can take.

Daily application of a broad-spectrum SPF 15 or higher sunscreen can be very useful. Be sure to keep an extra bottle in your car to re-apply every two hours.

You can also purchase a UV protection film for your car window, and be sure to keep your windows closed when the sun is highest in the sky during 10am to 2pm.
