Just how long have you been using sunscreen. I never used the stuff until about 15 years ago at the constant pressure by the wifey, bless her heart. I'm almost 60! She's a stickler now but I remember the day when her n the girls layed on the edge of the lake with baby oil on them! They looked great. There ain't no tannin booth made that can immitate the dark brown tan Ol Motha Nature produces.

Well I found this tid-bit today for my Old Stoner Friends..cheers..DD

Sunscreen may cause, not prevent skin cancer

As summer weather grows closer, more and more people are heading outdoors, exposing their bodies to the glowing sunshine. And according to materials released May 7, 2012 by researchers at Missouri University of Science and Technology sunscreen may not be protecting you from skin cancer—in fact, it may be causing it.

While some sun exposure can be enjoyable and even beneficial—like aiding your body’s production of vitamin D—too much can be very harmful. Both ultraviolet A (UVA) and ultraviolet B (UVB) radiation from the sun can result in sunburn, skin aging or problems and suppression of your immune system.

Sunscreens use active ingredients that either block absorption of harmful UV rays—physical—or absorb UV rays as they attempt to pass through them—chemical. Physical sunscreens are effective immediately, whereas chemical-based sunscreens take 20 to 30 minutes to be effective. Commonly used active ingredients in physical sunscreens include zinc oxide and titanium dioxide. Chemical sunscreens use a wide range of chemicals that block UVA, UVB or both rays at varying degrees.
According to the materials, Dr. Yinfa Ma, Curator’s Teaching Professor of Chemistry at Missouri University of Science and Technology, and his graduate student Quingbo Yang, discovered that zinc oxide undergoes a chemical reaction when exposed to sunlight that may release free radicals.

Free radicals are unstable molecules that cause damage to cells and DNA, leading to an assortment of diseases, such as cancer, Alzheimer’s disease and heart disease.

Ma and Yang suggest that this action could increase the risk of skin cancer. They studied how cells immersed in a zinc oxide solution reacted to exposure to UV light. They found that when these cells were exposed to UVA for three hours half of the cells died, whereas 90 percent of the cells died after 12 hours of exposure. All cells exposed to zinc oxide deteriorated more rapidly than those not immersed in the compound.

The researchers caution that their research is in the early stages and that wearing sunscreen is better than the alternative of full exposure to UV rays.

Other ways to protect yourself from the sun include wearing a wide-brimmed hat and clothing that offers greater coverage, limiting your sun exposure from 10:00 a.m. to 4:00 p.m. and protecting your eyes with sunglasses.

Ma’s research will be published in Toxicology and Applied Pharmacology, though no publication date has been set as of this writing.

Interesting. Been using it for decades. My kids have been splashed with it every time out for more than a few minutes since birth. I'll be watching this closely. In the meantime, I'll take their advice,

Well shit. I'm leaving for the beach tomorrow. Just gotta get that first summer burn then you're ok.

Think about the billions (trillions?) of hours of sunscreen use already under our collective first world belts over the last 40 or whatever years. Maybe this'll one day prove free radicals aren't as bad as first thought. My stoned thought contribution for the day. You're welcome

please say it aint so doobie!!!!!

i feel like the world is being un -nerfed one step at a time!

LOL .......i have never been a real fan of sunscreen so if it turns out that it does cause cancer i will be O.K. with it.... but i can't wait to see the line at the lawyers' offices if folks start blaming coppertone for making then think that UV was healthy

wow intresting stuff

Skin cancer survivor here. I just avoid the sun. And about half the time I still wear long sleeved shirts in the summer. Never felt good about putting all those chemicals on. Thought it was just a matter of time before someone looked at this possibility. That was 15 years ago. Ladies, pale is in, for better or worse. They say people will be slower to wrinkle as they age also, with less sun exposure. I've helped break the tanning booth habit for some friends after I've shown them the scar. And I thought I couldn't get any uglier. Wrong, but thats life. Footnote: I am a native of the sunshine state. Always outside swimming or something. Mom felt guilty about that after the biopsy. It was what we did in sixties. But still I admit, I like driving by places in the summer just to look at the girls sunning themselves. Oh well, the two edged sword.........(summer school at most local colleges will be starting soon, might take the long way home from work in a few weeks. I wave, I smile, I go on.....no, I cant whistle very good) my 2 cents

Duh.

It's myth-debunking time. Folks, this is NOT TRUE. Any color you get from the sun, red or brown, is skin damage, pure and simple. It doesn't matter whether it's your first sunburn/suntan of the summer or your fifth. Any and all color you get outside represents skin damage. It's a fact.

It wouldn't surprise me if sunscreen has possibly carcinogenic ingredients. All scented products are suspect nowadays. Still, I figure I'm more likely to get cancer NOT using sunscreen, and have no intention of stopping. I also wear long sleeves when I'm outside. Should really wear a hat, too.
