What Do you Know About Sunscreens?

The summer is here and as we travel on vacations or just enjoy the warm rays by the pool or beach locally we need to remember to protect our skin at all times. We are all aware that the sun is damaging but do we really know how damaging it is? Such as: Did you know 90% of skin aging is due to the sun? Did you also know that about 65% of melanoma cases can be attributed to ultraviolet (UV) radiation from the sun (skincancer.org)? The numbers are scary but with more knowledge, better decisions will be made (hopefully). Here are some facts about sunscreens from the Skin Cancer Foundation:

What Are Sunscreens?
Sunscreens are products combining several ingredients that help prevent the sun’s ultraviolet (UV) radiation from reaching the skin. Two types of ultraviolet radiation, UVA and UVB, damage the skin and increase your risk of skin cancer. Sunscreens vary in their ability to protect against UVA and UVB.

What Are UVA and UVB?
Ultraviolet (UV) radiation is part of the electromagnetic (light) spectrum that reaches the earth from the sun. It has wavelengths shorter than visible light, making it invisible to the naked eye. Ultraviolet A (UVA) is the longer wave UV ray that causes lasting skin damage, skin aging, and can cause skin cancer. Ultraviolet B (UVB) is the shorter wave UV ray that causes sunburns, skin damage, and can cause skin cancer.

What Is SPF?
SPF – or Sun Protection Factor – is a measure of a sunscreen’s ability to prevent UVB from damaging the skin. Here’s how it works: If it takes 20 minutes for your unprotected skin to start turning red, using an SPF 15 sunscreen theoretically prevents reddening 15 times longer – about five hours. Most sunscreens with an SPF of 15 or higher do an excellent job of protecting against UVB.

What Does Broad-Spectrum Mean?
Broad-spectrum sunscreens protect the skin from both UVA and UVB rays. Beginning in December 2012, the U.S. Food and Drug Administration (FDA) will implement new rules for “broad-spectrum” products.

Our favorite ingredients in sunscreens are zinc oxide and titanium dioxide (broad-spectrum), which are in Rhonda Allison’s Daytime Defense SPF 30 and eZinc Protection Cream.
Keep that in mind when picking out sunscreen.

    I am a beautician and I have studied some pharmaceutical sciences as well. This article really highlights the importance of sunscreens. Keep in mind though moisturizers help reverse skin aging by rehydration . It is best to mix your sunscreen with a little moisturizer to protect and heal your skin.
