Why You Need Sunscreen
005 ZORRO after the summer vacation by edart
It's summer, the weather's hot, the sun is bright, and people are a little lazier (or maybe just me). But just as I was slacking a bit from wearing sunscreen everyday, I came upon an article on The Body Odd showing a picture of a 69 year old truck driver's skin after 25 years of daily sun exposure.
Here it is:
(via The Body Odd and the New England Journal of Medicine)
As a delivery truck driver for the past 25 years, the UVA rays shining through the truck window caused severe wrinkling on the left side of his face. (The longer UVA rays penetrate deeper into the skin and cause over-aging. The shorter UVB rays cause sunburn and skin cancer. So just because you avoided the UVB rays and didn't get sunburned doesn't mean you were untouched by sun damage at all). To read the entire article for all the details, click here.

Now then, what kind of sunscreen to get? There are chemical sunscreens and physical sunscreens. Chemical sunscreens contain (you guessed it) chemicals that are absorbed into your skin, which then absorb UV rays instead of letting it penetrate deep into your skin layers. Physical sunscreens contain titanium dioxide and/or zinc oxide, which sit on top of your skin and block out UV rays. I prefer physical blockers because I think that I have enough things getting absorbed into my skin (from all my moisturizers and stuff), so it's nice to have a shield of metal over all of that :) But I'm not the expert, so you should consult a dermatologist for all of your questions. Here is a great site that I used to learn about the UV rays and different types of sunblocks. Check it out yourself at: Understanding UVA and UVB - SkinCancer.org!
