Let the sun Shine! It’s getting sunnier now and that means we need to be sure to wear Sunscreen! The sun is the main contributor to our skin looking aged and prematurely aging. You can’t stop your body from naturally aging. But you can control how much sun damage you get. Wearing sunscreen is such a simple yet effective way to slow down skin aging.
UV radiation in sunlight is a major trigger of free radicals. When UV radiation contacts skin, it reacts with oxygen in the air, which causes a free radical chain reaction.
Free radicals are bad. Really bad. They are unpaired electrons that attack everything around it, rendering them dysfunctional. The things in our skin that are effected are proteins such as collagen and elastin, epidermal lipids, membrane lipids, mitochondria, other cellular organelles, and worst of all, DNA.
There are two kinds of SPF’s to choose from. One is a chemical block and the other is a physical block. If you’ve ever applied sunscreen and still got burnt, you must consider how old the product is, how long since the application, if you’ve sweat or gone into water (even if it is water resistant) and if it is a chemical block or physical block. If the product is a year or older, it’s only half the SPF it claims to be. So if it says 50 SPF and it is from last summer, this summer it is only 25 SPF.
If your unprotected skin turns pink in the sun in 10 minutes, then multiply the SPF times 10 minutes. So SPF 30 multiplied by 10 would be 300 minutes of protection. If you sweat or go into the water, it’s halved. You would now be protected for 150 mins (minus the minutes you’ve already been in the sun). So always reapply regularly!
If you’ve ever burnt and were within the limits of protection, you might try a physical block SPF as sometimes the more commonly used chemical SPF can actually breakdown in the sun and not protect as it should.
So, there is a lot to consider when going out in the sun and when selecting a good SPF. Read reviews or book in for a consultation with your skin specialist for options and advice.
