Are You a Shaver, Waxer or Plucker?

In 1995, however, a much longer-lasting hair removal process was introduced to the US consumer market. The ThermoLase Corporation of San Diego, California was the first company to receive FDA clearance for its hair removal device. The method suggested use of infrared (IR) laser light in conjunction with a topical light absorbing solution. Though the long lasting effects of that first laser hair removal approach were questionable (in terms of its comparison with electrolysis), its speed and virtual painlessness were so desirable that laser hair removal soon became very popular. It was also quickly determined that the best results in hair removal could be achieved only when the unique laser light property is correctly utilized. The fact that laser emits its light energy in a very narrow spectral range (usually represented in laser specifications by peak emitting wavelength), makes it possible to effectively deliver laser energy right to the hair follicle, without damage to surrounding skin layers.

Since 1997, many companies in the United States and Europe have introduced new laser hair removal devices. The lasers for hair removal today come in all shapes and sizes, and there are also different lasers that use different wavelengths of light. Some utilize a cooling device and some do not. But all laser systems emit a gentle beam of light that passes through the skin to the hair follicle where it is absorbed by the hair. Among all these systems, the Alexandrite laser-based devices have attracted the biggest market share.

So what does all of this mean to you, the person with the unwanted body hair? First of all, let’s take a quick look at what laser hair removal actually does. Basically, laser hair removal is a medical procedure that uses laser light—a pulsating, intense beam of light—to remove unwanted hair. It works by passing a light beam through the skin and targets dark pigment in hair called melanin. When the light beam hits the hair follicle (where hair growth originates), the intense heat destroys the hair follicle or papillae instantly. It should be noted, however, that hairs that may have been dormant during a previous laser hair removal session may later be in the growth phase and re-grow. In most cases, laser hair removal slows hair re-growth, but it takes several treatments to provide an extended "hair-free" period. Although laser hair removal doesn't guarantee permanent hair removal, it does much to extend a hair-free period, which can vary from a few months to many years. And with multiple treatments, long-term hair removal is possible.
What are typical areas of unwanted body hair? Common treatment locations include certain areas of the face such as the upper lip and chin, the armpits, legs, back and for women, the bikini line. It is possible, however, to treat unwanted hair on almost any area of the body. Here are three other common questions about laser hair removal:

1. Will it hurt? The answer is that most individuals experience no more than a slight stinging sensation as the procedure is applied (sometimes described as similar to how popping a rubber band to the skin might feel). Some parts of the body can tend to be more sensitive than others and a topical numbing cream is available for those who feel the need for a lessening of unpleasant sensations. A preparation of natural aloe vera can be very effective for this purpose.

2. How many laser hair removal sessions does it take? The number of treatments required for long-term benefits depends on the location of the treatment, the hair's growth cycle, and your individual hair density. There are three phases of hair growth — Anagen (active), Catagen (regression) and Telogen (resting). Laser technology is designed to treat hair in the Anagen phase of growth. Additional factors including ethnicity, age, diet, hormones, weight, metabolism and medication can influence hair growth and play a role in the location, thickness and resilience of your hair. Although each person is unique, you can most likely expect an average of 4-8 treatments, probably spaced about 6 to 12 weeks apart, depending on the location on the body of the unwanted hair.

3. What are the risks of laser hair removal? Hair color and skin type are the key factors that influence the success of laser hair removal. It is generally most successful on people with dark hair (brown or black) and light skin. However, it can also be used safely on people with darker skin types. Lightening of the skin (known as hypopigmentation) is of special concern with people who have darker skin. Laser hair treatment is more successful on fair skin, but darker skin also can be treated. Laser hair removal does not seem to work for white, blonde, light brown or light red hair.

To reduce your risks, make sure you choose a qualified, trained doctor who is board-certified in dermatology or a similar specialty. Your doctor should meet with you before the procedure and determine your treatment plan. If a physician's assistant or licensed nurse performs the procedure, your doctor should supervise and be available on-site during the treatments. It is not wise to go to a spa, salon or clinic that allows non-medical personnel to perform this procedure. Complications from laser hair removal are rare if you go to a qualified doctor. Bleeding during the laser treatment is extremely rare, as is the possibility of infection resulting from treatment. Overall, laser hair removal treatments are considered quite safe. Just make sure to talk with your health care practitioner to understand how some of the risks may apply to you.

Laser hair removal technology continues to evolve. No matter what skin type you have, newer lasers can safely and effectively remove unwanted hair from your face and body.
