Sun Protection Facts You Must Know This Summer

August 23, 2016

 

With the heat of summer upon us, it is more important than ever to take care of your skin while in the sun.

Sunburned skin can lead to wrinkles, crows feet, liver spots, fine lines, and can require expensive anti- aging treatments to reverse them. In fact, a whopping 90% of visible changes commonly attributed to skin aging are actually caused by the sun! 

So to better practice summer skin care, here are some sun protection facts you must know for next time you step outside.
 

UVA vs. UVB
It is important to understand the difference between these two rays that come from the sun. UVA rays affect the under layers of the skin, which leads to premature aging. On the other hand, UVB poses a risk to the top level of skin and will cause your skin to burn. Both are equally as dangerous, and dermatologists recommend using sun protection that protects against both types.
 
Sunscreen vs. Sunblock
Contrary to popular belief, sunscreen and sunblock are not the same thing. Sunscreen contains chemicals that absorb ultraviolet rays before they damage the skin, whereas sunblock has particles in it to form a physical wall against the UV rays. Generally speaking, sunscreen needs about 30 minutes after application to be effective, whereas sunblock starts working immediately.
 
The higher the number, the better off you are
Sunscreen and sunblock comes in different SPF protection levels, with the lower numbers representing less protection. But in this case, a little can go a long way. Those who use sunscreen with an SPF of at least 15 show 24% less skin aging than those who do not use protection. But for the utmost anti aging protection, doctors recommend staying in the shade, wearing protective clothing, and applying SPF 30.

Additionally, the SPF numbers indicate how long you can be in the sun before you start to burn. For example if you burn after 10 minutes of being in the sun without protection, applying SPF 15 means you can be exposed for 15 times longer than normal. The higher the number, the longer lasting the protection.
 
Reapplying does not mean more protection
It is important to reapply your sunscreen or sunblock after you get in the water, but doing so will not give you extra sun protection. It will only ensure you are protected with the original SPF you chose.

So keep these tips in mind, and you will stay protected from the sun all summer long.
