Sunscreen 101: A beginners guide to choosing a suncreen

Spring is here and will soon turn into summer, and swim suits will come out of hibernation. This then, is a good time to educate ourselves in sunscreens. Lets get right into it. There are two kinds of sunscreens, chemical and physical. Chemical sunscreens are absorbed by the skin and chemicals then absorb UV rays to protect your skin.
 
Physical sunscreens form a protective barrier on your skin and usually deflect or block the UV rays.
 
So far so good. Seems that both types are giving you benefits of UV protection. Let's dig deeper!
 
Physical sunscreens can be made of Titanium dioxide (TiO2) or Zinc oxide (ZnO). Chemical sunscreens can be made of Avobenzone, Oxybenzone, Octisalate and the list goes on! Most common chemicals I have seen being used in sunscreens are the above three.
 
Why am I talking about these ingredients you might ask! Here is why. The problem with chemical sunscreens is they get absorbed in your skin and can interact with your DNA. Yes! You read correctly your DNA. They can metabolite to produce free radicals and behave as carcinogens themselves. Same is true for Vitamin A, also known as Retinyl palmitate found in sunscreens. It can also harm your DNA. And you know how protective I am of the DNA ;)
 
More then half of the chemical sunscreen can cause hormonal issues and imbalance.
That's not all, chemical sunscreens find their way into your blood, urine and even breast milk if you are breastfeeding, AND can hang out in your body for up to 2 days after a single application. OUCH!
 
Preventing cancer from UV, but causing cancer by damaging DNA or at the very least, aging your skin faster and/or irritating your skin, not good news then is it?
 
y rule of thumb is to avoid chemical sunscreens. At first I used to just think of SPF factor, the higher the SPF the better.  But, I found out that an SPF between 30 and 45 is all you need anything higher is just a marketing ploy.
 
Physical sunscreens are the way to go, but the white tint is a big no-no for fashion forward people like me ;) So I went on a search for a perfect sunscreen.
 
My search brought me to MyChelle, it is a physical sunscreen that does not leave a white tint on your face and it has moisturizing components as well.
 
There are other sunscreens that might work for your skin as well, the best thing to do is look for Titanium dioxide and Zinc oxide as active ingredients and absence of Vitamin A or any other harmful chemicals like dimethicone. More on that another time.
 
If you have any questions on how to choose a good sunscreen write them in the comments section and I will try my best to answer them for you.
 
Enjoy the sun and be SAFE.
