Need sunscreen advice...

[DennisAJC]

Does sunscreen prevent tanning? Or does it just protect from skin cancer or other stuff. I was shocked not to know this answer.

I've never used it before but after driving around this past few days, my left arm looks extremely dark as opposed to the rest of my body. I need to stop this process. It's really noticable when I stand naked in front of the mirror before I take a shower.

Any advice? Serious question.

if you go with a high SPF yes it will keep you white as a ghost. We usually slather up the kiddo at the beach with like 40SPF or something like that.

So the wife isnt diggin the trucker tan you have?

Thanks! The word melanoma makes me crave for watermelon for some reason.:D

Nope. She's not diggin it at all. The shirt line making it look like I dipped my arm in sh1t.:clapping: Thanks for the advice.

It's called Golden Tan and it's all season. Filippinos aren't yella!:fdance:

You know we all missed the simplest solution to the trucker tan....keep the arm inside the truck with the window up......LOL....

Its been raining so much here in pittsburgh I forgot what the sun even looks like!

Hi DennisAJC,

Sunscreens do protect skin from sunburn, but a scientific debate simmers about the role of lower-energy ultraviolet light in skin damage and whether current sunscreens provide adequate protection.
In recent years, however, it has become apparent that a different form of ultraviolet light, called UVA, may be even more important in causing some skin disorders. Although experts still believe that UVB is responsible for much of the skin damage caused by sunlight -- especially sunburn -- UVA may be an important factor in photoaging and skin cancers. Most sunscreens do a good job blocking UVB, but fewer sunscreens filter out most of the UVA, so they do not help to prevent the beginnings of melanoma formation.
The death rate from melanoma in the US has increased by about 4% a year since 1973, according to the Centers for Disease Control and Prevention. Melanoma represents only about 47,000 of the 1.8 million cases of skin cancer diagnosed each year, but according to the American Cancer Society it will cause 79% of skin cancer deaths. While cancer treatments continue to improve, melanoma recovery rates remain disappointing. Prevention is the better solution.
As prevention, however, sunscreens alone appear to be imperfect. In the first study to test the protective effect of sunscreens on people -- not just the hairless mice used in laboratory studies -- researchers at the Queensland Institute for Medical Research in Brisbane, Australia, reported in 1999 that sunscreen use reduces the risk of developing squamous cell carcinoma by 40%. But using sunscreen did not reduce the risk of developing melanoma or basal cell carcinoma. The Australian study followed 1,383 adults for five years.
According to the Food and Drug Administration (FDA), sunscreens are an important part of a person's total sun protection strategy, but sunscreen alone will not prevent all of the possible harmful effects due to sun exposure. Borrowing the "Slip, Slop, Slap" slogan from an Australian skin cancer prevention campaign, the American Cancer Society recommends that anyone out in the sun slip on a shirt, slop on sunscreen and slap on a hat. The educational campaign in Australia seems to be working: the rates of skin cancer are declining in younger groups, and suntans are out of fashion. But the melanoma rates are still high in older people whose skin was damaged by sun exposure years ago.
Physicists classify ultraviolet light into three types, by its wavelengths: UVA, UVB and UVC. The dimensions of their wavelengths are roughly 400 to 320 nanometers (nm) for UVA, 320 to 290 nm for UVB, and 290 to 200 nm for UVC. Although it may seem backwards, the shorter the wavelength and the lower the number, the greater the energy level of the light and the more damage it can do. For example, direct exposure to UVC for a length of time would destroy the skin. Fortunately, UVC is completely absorbed by gases in the atmosphere before it reaches the ground.
The longer wavelengths of UVB and UVA pass right through the atmosphere, even on a cloudy day. That's why you can still get sunburned on a cloudy or hazy day. The molecules in sunscreens absorb most UVB and prevent it from reaching the skin just as the molecules of the atmosphere absorb UVC and prevent it from reaching the ground. But UVA is another story.
Most sunscreens do not protect the skin from the longer UVA wavelengths. And that may be critical to the creation of skin cancer. Approximately 65% of melanomas and 90% of basal and squamous cell skin cancers are attributed to UV exposure. The precise wavelengths of ultraviolet that contribute to the formation of skin cancer still need to be sorted out. And scientists must still figure out how best to formulate sunscreens to provide effective protection against these wavelengths. Scientists lack a simple measure of UVA's impact on the skin, and that makes it difficult to determine how much UVA protection a sunscreen provides.
To figure out how much protection a sunscreen provides, most of us look at the number on the label: the SPF, or sun protection factor. And studies show that most people understand that the higher the number, the more the product protects the skin. But studies also show that people often have the mistaken notion that the higher the SPF number of the sunscreen they use, the longer they can stay -- and do stay -- in the sun. Sunscreen should not be used to prolong time spent in the sun.
The FDA hopes to resolve some of the controversy so sunscreen labels of the future will be clear, reliable, and easy to understand. Products that claim "all day protection" and "broad spectrum sunblock" will have been tested to meet specific standards for blocking UVA, not just UVB. And when the label says "water resistant," it must mean that the product provides the stated SPF level after water resistance testing for a specified length of time.

Hope this helps...

Thanks buddy!:beerchug:


I think I'll try out the "Caucasian Pink" :clapping:

Alot depends on length of exposure and spf rating, I used to do alot of South American surfing and I would use a product called Aloe Gator 40+ super waterproof sunblock gel (its the best stuff ever imo, apply 20 min prior to exposure and it really last all day. But it must be gel no lotion.) after surfing all day for 2 weeks I was tan but not dark.

be very careful, mike wallace reported that some of it is made from monkey jism...
