   Coloring Agent As summertime gets closer more and more people are hitting the tanning salons trying to get that perfect glow. Here are some things you should know about indoor tanning.If you are go to a tanning salon one of the most important things to make sure that you have is protective eyewear. Some people think that a towel or closing their eyes is good enough however your eyelids and towels do not provide UV protection. The eyewear has 100 percent UV protection. The delicate eye tissue can be damaged by overexposure to UV light, causing basal cell carcinoma. The UV light can also cause you to loose your night vision and diminish your color vision. There is no cure for either of these problems. It can also cause photokeratitis — which is a temporary corneal burn resulting from short term over exposure to UV light. The result is a tearing pain and blurring for two or three days – or cataracts, which are permanent damage to the cornea resulting from long-term UV light. The only cure for cataracts is surgery. Eyewear should even be worn if you are only using the leg tanner because of the radiation and still being able to see the light from the UV lamps.Some people are allergic to tanning which could be because of medications they are on or from lying directly over the bulbs. These people could try airbrush tanning, mystic tanning or stand up tanning booths.Airbrush tanning is more expensive and does not protect you from burning in the sun as it dyes your skin rather than creating melanin. Melanin is what your body produces that causes you to be tan to protect your skin from burning. A DHA formula is used for airbrush tanning and is also found in a lot of tanning lotions used for tanning beds. DHA stands for Dihydroxyacetone, which was first recognized as a skin-coloring agent back in the 1920s by German scientists. Since it was used for the X-ray process, it was noted as causing the skin to turn brown when it was spilled.Mystic tanning is similar to airbrush the only difference between the two being that when airbrushed another person is actually spraying the DHA formula on you. Mystic tanning is where you stand in a booth and the machine sprays you. Airbrush tanning is better than mystic for the simple fact that having a person spraying the DHA formula on you gives a more even tan then a machine.There are several different types of tanning beds. Some salons have leg tanners since the legs exfoliate more often for women due to shaving. Stand up tanning booths can allow more space from the bulbs and may prevent the allergic reaction for some people. The standing bed also gives you a more even tan preventing the pressure lines and lines under the arms and down your sides. They also have high-pressure beds that use quartz lamps. These beds are called high-pressure beds because of the manufacturing process of the bed, which maintains the gases in the lamps at above atmospheric pressure while gases in conventional beds are held below atmospheric pressure.Tanning beds consist of two types of rays, UVA rays and UVB rays. UVB rays are tanning rays that are only strong enough to make it through the epidermis. The UVB ray is what stimulates the melanocyte cell and helps produce melanin as mentioned earlier. UVA rays go through the epidermis and scatter through the dermis, which is the second layer of skin. The UVB ray is more damaging to the skin than the UVA ray. The UVB ray is referred to as the burning ray and UVA ray is referred to as the tanning ray, it also gives you a deeper tan.Another thing that is very important to know about tanning is that it dries the skin out so moisturizing is very important. Not only that but also getting into a tanning bed without the skin being moisturized will not give you as good of a tan because your skin will reflect the rays, whereas if your skin is moisturized it will absorb them, making tanning more effective.Because of the potential dangers, you should use the tanning bed in moderation..
