The Difference Between UVA and UVB Ultraviolet Rays and How They Can Harm Your Skin!

We all enjoy soaking up the sun and getting a nice summer glow; however, this summer glow can produce some very unappealing short and long term effects. Last week we discussed the SPF factor of your sunscreen and how to apply sunscreen correctly.  This week we want to clear up the subject of UVA and UVB rays and how they effect your skin.

First of all, what is a "suntan?"  A suntan occurs when ultraviolet light penetrates the epidermis causing the skin to produce melanin.  The increase in melanin is what gives your skin a darker tint or a "suntan."  This doesn't sound harmful, right? Well, unfortunately the ultraviolet rays that are penetrating your skin can be very harmful, both short term and long term.  Here's a quick lesson on the different types of rays and how they can effect your skin. 

The sun produces three types of rays;  UVA, UVB & UVC.  UVA is a long ultraviolet wave, UVB is a shorter ultraviolet wave and UVC is the shortest ultraviolet wave.  UVA rays are the rays that cause long term effects by aging our skin.  UVB rays are the rays that cause the skin to "burn" but can also cause long term damage to the skin.  The UVC rays are the strongest but do not typically reach the earth and are absorbed by the ozone. 

UVA rays are able to penetrate the dermis (the thickest part of your skin) very deeply.  The rays will not only cause premature aging but can also break down the immune system which can put you at risk for skin cancer.

UVB rays cause the most damage to the superficial layers of the skin and are the rays that cause you to "burn." These rays have fluctuating intensity depending upon the season, location and time of day.  They typically reach their peak between 10 am and 4 pm.

Since BOTH rays are harmful to your skin, it is imperative to find a quality sunscreen that will protect against both UVA and UVB rays.  These products should be marked as broad spectrum or specifically state they protect against both types of rays.  We carry a variety of quality UVA/UVB sunscreens by some of the most trusted names in skin care like Jane Iredale, Obagi, Skinceuticals, Tizo and Hydrafacial.
