By Taylor Kubota for Men's Journal. In the early '50s, Coppertone began selling the first commercially successful sunscreen -- and followed that up with the first sunless tanner for consumers just 10 years later.

Tans in a bottle and sun bathing have battled it out ever since. Neither is necessary -- healthy skin trumps sun damage any day -- but for those chasing a golden glow, which tanning method is healthier?

Sun tanning can cause skin cancer, premature aging, cataracts and immune system suppression -- not to mention painful burns. To avoid these consequences, everyone over the age of six months should wear sunscreen with an SPF of 15 or higher every day, according to health experts. It should be applied 30 minutes before you go outside and reapplied every two to three hours you're in the sun.

A small-scale study found that if you aren't lathering daily, you could be doubling your chance of developing melanoma, the deadliest form of skin cancer. But if you are using the wrong brand, you may be exposing yourself to harmful chemicals. David J. Leffell, professor of dermatology and surgery at the Yale School of Medicine.

Just one bad sunburn significantly increases a person's risk of developing skin cancer later on. Once hailed as the smart alternative to tanning outside, spray tans can also be hazardous to your health.

The concern stems from use of dihydroxyacetone DHA in tanning solutions, which interacts with dead cells on the skin's surface to evoke color change. When used properly, DHA is considered safe.

But many people don't use spray tans properly. Lab studies have shown that high levels of DHA -— much higher than you'd find in over-the-counter tanning products -— can increase free radical formation. Free radicals are part of our natural metabolic process but high levels have been linked to cell damage and cancer. The bottom line: You may have to stuff tissues up your nose and live with pale eyelids, but if you're looking for the safest tan, a cautious application of tan in a bottle is probably best method.

Sun tanning - Wikipedia

Sun tanning or simply tanning is the process whereby skin color is darkened or tanned. It is most often a result of exposure to ultraviolet UV radiation from sunlight or from artificial sources, such as a tanning lamp found in indoor tanning beds.

People who deliberately tan their skin by exposure to the sun engage in a passive recreational activity of sun bathing. Some people use chemical products which can produce a tanning effect without exposure to ultraviolet radiation, known as sunless tanning. Moderate exposure to direct sunlight contributes to the production of melanin and vitamin D by the body , but excessive exposure to ultraviolet rays has negative health effects, including sunburn and increased risk of skin cancer , [1] as well as depressed immune system function and accelerated aging of the skin.

This may be the result of different skin types and natural skin color , and these may be a result of genetics. The term "tanning" has a cultural origin, arising from the color tan. Its origin lies in the Western culture of Europe when it became fashionable for young women to seek a less pale complexion see Cultural history below.

Melanin is a natural pigment produced by cells called melanocytes in a process called melanogenesis. Melanocytes produce two types of melanin: pheomelanin red and eumelanin very dark brown.

Melanin protects the body by absorbing ultraviolet radiation. Excessive UV radiation causes sunburn along with other direct and indirect DNA damage to the skin, and the body naturally combats and seeks to repair the damage and protect the skin by creating and releasing further melanin into the skin's cells. With the production of the melanin, the skin color darkens. The tanning process can be triggered by natural sunlight or by artificial UV radiation, which can be delivered in frequencies of UVA, UVB, or a combination of both.

The intensity is commonly measured by the UV Index. There are two different mechanisms involved in production of a tan by UV exposure: Firstly, UVA radiation creates oxidative stress, which in turn oxidizes existing melanin and leads to rapid darkening of the melanin. UVA may also cause melanin to be redistributed released from melanocytes where it is already stored , but its total quantity is unchanged.

Skin darkening from UVA exposure does not lead to significantly increased production of melanin or protection against sunburn. In the second process, triggered primarily by UVB, there is an increase in production of melanin melanogenesis , [3] which is the body's reaction to direct DNA photodamage formation of pyrimidine dimers from UV radiation. Most UVA is not blocked by the atmosphere's ozone layer.

UVA causes the release of existing melanin from the melanocytes to combine with oxygen oxidize to create the actual tan color in the skin. However, it operates not by inducing direct DNA damage, but by producing reactive oxygen species which damage DNA indirectly.

UVA see above induces a cosmetic tan but little extra melanin protection against sun damage, sun burn, or cancer. Much of this band is blocked by the Earth's ozone layer, but some penetrates. A person's natural skin color affects their reaction to exposure to the sun. An individual's natural skin color can vary from a dark brown to a nearly colorless pigmentation, which may appear white. In , Harvard dermatologist Thomas B.

Fitzpatrick devised the Fitzpatrick scale which described the common tanning behavior of various skin types, as follows: [9] [10]. The most common risk of exposure to ultraviolet radiation is sunburn , the speed and severity of which vary among individuals.

This can be alleviated at least to some extent by the prior application of a suitable-strength sunscreen , which will also hinder the tanning process due to the blocking of UV light. Overexposure to ultraviolet radiation is known to cause skin cancer , [11] make skin age and wrinkle faster, [12] mutate DNA , [13] and impair the immune system.

The study suggests that the melanoma risk is linked more closely to total exposure than it is to the age at which an individual first uses a tanning bed. Production of vitamin D is essential for human health. Moderate exposure avoiding sunburn to UV radiation provides benefits such as increased vitamin D, as well as other possible benefits that are still being studied. Several tanning activators have used different forms of psoralen , which are known to be photocarcinogenic.

Tanning has gone in and out of fashion. In the United States and Western Europe before about the s, tanned skin was associated with the lower classes, because they worked outdoors and were exposed to the sunlight. Women went to great lengths to preserve pallid skin, as a sign of their "refinement". Women's outdoor clothing styles were tailored to protect against sunlight exposure, with full-length sleeves, and sunbonnets and other large hats, headscarves, and parasols shielding the head. Women even went as far as to put lead-based cosmetics on their skin to artificially whiten their skin tone.

Light-skinned appearance was achieved in other ways, including the use of arsenic to whiten skin, and lightening powders. The preference for fair skin continued until the end of the Victorian era. By the early 20th century, the therapeutic benefits of sunlight began to be recognized.

Vitamin D deficiency was found to be a cause of rickets, and exposure to sunlight would allow vitamin D to be produced in a person. Therefore, sunlight exposure was a remedy to curing several diseases, especially rickets.

In a scientific expedition went to the island of Tenerife to test the wider health benefits of "heliotherapy", [28] and by "sunbathing" was referred to as a desirable activity for the leisured class. Shortly thereafter, in the s, fashion-designer Coco Chanel accidentally got sunburnt while visiting the French Riviera.

When she arrived home, she arrived with a sun tan and her fans apparently liked the look and started to adopt darker skin tones themselves. In addition, Parisians fell in love with Josephine Baker , a "caramel-skinned" singer in Paris , and idolized her dark skin. These two women were leading figures of the transformation that tanned skin underwent, in which it became perceived as fashionable, healthy, and luxurious.

Just before the s, sunlight therapy became a popularly subscribed cure for almost every ailment from simple fatigue to tuberculosis. In the s, advertisements started appearing in women's magazines which encouraged sunbathing. At the same time, swimsuits ' skin coverage began decreasing, with the bikini radically changing swimsuit style after it made its appearance in In the s, many people used baby oil as a method to increase tanning.

The first self-tanner came about in the same decade and was known as "Man-Tan", although it often led to undesirable orange skin. In , Mattel introduced Malibu Barbie , which had tanned skin, sunglasses , and her very own bottle of sun tanning lotion. In , there were an estimated 50, outlets for indoor tanning; it was a five-billion-dollar industry in the United States, [36] and had spawned an auxiliary industry for indoor tanning lotions including bronzers, intensifiers, and accelerators.

Since then, the indoor tanning industry has become more constrained by health regulations. As recently as , in some parts of China, ski masks were becoming popular items to wear at the beach in order to protect the wearer's face from the effects of sunlight. A innovation is tan-through swimwear , which uses fabric perforated with thousands of micro holes that are nearly invisible to the naked eye, but which transmit enough sunlight to approach an all-over tan, especially if the fabric is stretched taut.

Tan-through swimwear typically allows more than one-third of UV rays to pass through equivalent to SPF 3 or less , and an application of sunscreen even to the covered area is recommended. To avoid exposure to UVB and UVA rays, or in seasons without strong sunshine, some people take alternative steps to appear with darkened skin. They may use sunless tanning also known as self-tanners ; stainers which are based on dihydroxyacetone DHA ; [42] or cosmetics such as bronzers.

Many sunless tanning products are available in the form of darkening creams, gels , lotions , and sprays that are self-applied on the skin. From Wikipedia, the free encyclopedia.
