The History of Laser Hair Removal

The lasers used for laser hair removal developed from a theory instituted by the Nobel prize-winning physicists Albert Einstein and Max Planck. This theory, first introduced in the 1920s, defined stimulated emission, or laser. The word laser is an acronym for light amplification by stimulated emission of radiation. However, it wasn’t until the 1960s that the first true laser was built and patented by Gordon Gould, an American physicist.

Laser hair removal devices of the 1960s sent out a continuous wavelength which caused damage to the surrounding skin tissue. In the late 1960s, Dr. Leon Goldman was the first to begin testing a ruby laser for hair removal. It was also in this time frame that the Q switch with developed for use with a laser. With the development of the Q switch it was possible to control the energy of the laser beam to be sent to out in controlled pulses. The Q switch worked much in the same way as a camera shutter.

Early devices for laser hair removal proved to be ineffective. In order to remove the hair follicle, there was severe damage to the surrounding skin area. The ruby laser, as well as the argon laser, are no longer used for laser hair removal.

Throughout the next several decades, researchers and physicists continued to experiment and test lasers for successful hair removal. It wasn’t until the 1980s that the first laser was introduced as a safe and effective method of hair removal. This discovery actually happened by chance when scientists noted that birthmarks treated with certain types of lasers caused the hair in that area to disappear and not grow back.

The FDA cleared the first laser for hair removal in 1995 . This laser, called the Soft Light, was a NeoDymium Yttrium Aluminum Garnets laser and was manufactured by Thermolaise. This laser was used with a chromophore of carbon-based lotion. After the skin was waxed, the carbon-based lotion would be rubbed onto the skin and enter the hair follicle. The beam of light produced by the laser would heat the carbon quickly and destroy the hair follicle. However, this type of laser treatment could easily damage nearby skin cells. Eventually, this type of laser hair removal proved to be less effective than targeting the natural pigmentation that existed in the skin.

In 1997, several types of laser hair removal devices were cleared by the F DA. One of these was the ruby laser, which used a shorter wavelength system. However, clinical research eventually showed that the laser did not produce damage far enough down the hair shaft to result in permanent hair loss. Researchers also found that if a t the ruby laser was used on people with dark or tan skin there was a high risk of hyperpigmentation. Other types of laser hair removal devices today include alexandrite, diode, and NeoDymium Yttrium Aluminum Garnets lasers.

Research and development in the area of laser hair removal are still in the early stages. However, continuing research, testing and development in this area continues to produce safer and more effective equipment.

The Cost of Laser Hair Removal

The cost of laser hair removal depends on several factors including the area to be treated, the amount of hair growth on the area, the number of treatments needed, the type of laser used, the individual physician or practitioner, and your geographic location. Laser hair removal can be quite expensive, but many people feel that the results are well worth the expense. This is because results of the treatment have a long-lasting effect. It also produces a reduced hair growth.

Because every individual is different and is going to require laser hair removal treatments specifically geared to their unique hair patterns, the price ranges included in this article are average costs. If you are considering laser hair removal, it is important to set up an appointment with your physician to discuss all of the aspects of the procedure, including the costs.

Because laser hair removal is usually considered a cosmetic procedure, it is not covered by insurance. Each laser treatment is separate and usually incurs a separate charge, unless a specified treatment package has been purchased.

Generally the most expensive areas to treat with laser hair removal is the complete face and neck, back, and legs. The average cost of one treatment for complete face and neck or back hair removal ranges from $600 and $900. Laser hair removal for upper and lower legs each cost from $600 to $850 for each treatment.

Laser hair removal for chest hair costs between $350 and $600 per treatment. This is also the approximate price range for each treatment of the arms. Treatments for the bikini area can range from $350 to $550. The cost of underarm hair removal generally is between $250 and $350 per treatment. Treatments for smaller areas, such as the chin or upper lip, cost between $100 and $175 per treatment.

The national average for the cost of a laser hair removal treatment is $429. Each region of the country has a different average cost per treatment. In the Eastern part of the United States, the cost per session is $425, compared to the Midwest, where it is $450. In the Western region of the country, the average cost per treatment is $420, slightly above that of the South, which is $400.

Fees vary even within each individual region. One of the factors that causes this to occur is the location of the physician’s, or practitioner’s office. The fees that are charged for an office in an urban area are going to be different from those charged for offices located in rural or suburban areas. Another determining factor for the variance in fees within the same region is whether or not the doctor owns or rents the laser equipment.

Another determining factor is the choice of place to have the laser hair removal treatments. A luxury spa will obviously charge a higher fee then a clinic. A doctor who does the procedure himself may charge more then a laser practitioner, or a physician that oversees the laser hair removal treatments provided by a qualified technician.

What is True About Intra Lasik?

Now that Lasik vision correction surgery has been accepted for a number of years, there are several popular options for the procedure. One of these is IntraLasik, or Intralase, or bladeless Lasik. As the name implies, there is no cutting of the eye with a blade, instead the flap in the eye is made using a laser. Since bladeless Lasik is a newer procedure, there are a number of opinions around about how well this procedure works. Let’s look at several of these and determine which of these are true or false.

First, more Lasik clients get 20/20 vision or better using IntraLasik. Any Lasik procedure cannot guarantee perfect vision for every client, though more than 90% get results to at least 20/40 vision. However, it is true that the new techniques of IntraLasik do get even better statistics for giving clients clear vision.

Some are concerned that the laser that makes the corneal flap is standard, and cannot be tailored to each individual eye like can be done by the Lasik surgeon when using a blade. This is not true. The Lasik physician has control over the use of the laser for each individual in the same way that he can control the microkeratome blade.

IntraLasik can be used for both a standard and a custom Lasik procedure. This is true. Custom Lasik procedures using Wavefront technology (another somewhat recent advance in Lasik vision correction) can easily be used with a laser making the initial flap. This custom Lasik procedure, though more costly, is of great benefit for people with unusual eye shapes or problems.

Some have heard that using the laser is less accurate than the standard Lasik procedure. This is not true, since lasers can be controlled to micron level accuracy. This gives the Lasik physician extreme control to create exactly the flap needed for this particular individual eye: the precise size, shape, and depth for successful completion of the Lasik procedure.

Another common fallacy is that IntraLase has not been around long enough for trusted Lasik physicians to have confidence in it. On the contrary, many of the most honored Lasik physicians strongly endorse IntraLase due to the track record of very good results from the Lasik procedures. In addition, the quality of the machines and the precision that they give these Lasik physicians is very impressive. Many of the top flight Lasik doctors recommend this as a procedure of choice, assuming cost is not a significant variable in the decision of which Lasik procedure to use.

Similar to the objection above, some people think that Intralase is not a sufficiently test Lasik procedure option. On the contrary, more than one million of these procedures have been performed, and the impressive track record for this Lasik procedure has been discussed above. More and more Lasik physicians are trained in this option, and we will see many more such Lasik procedures in the future.

We hope that this discussion of bladeless Lasik has given more accurate information to those considering this Lasik technique. Please discuss this option with the professionals at your local Lasik center.

Popular Teeth Whitening Treatments

A lot of people desire to have a brilliant smile with shiny and sparkling bright teeth. To achieve it, they consume lots of money on teeth whitening products. Teeth bleaching is just one of the few teeth whitening treatments.
