There are several ways to remove unwanted hair from your body such as shaving, using tweezers, or waxing. However these methods are by no means permanent and you will probably dread having to do them again in a few weeks. There is however one very popular technique that can be considered permanent and that is laser hair removal.
Lasers use concentrated amounts of light to destroy the hair follicle beneath the skin so that it will not grow back. You can treat any part of the body such as the face, arms, legs, bikini area, and under the arms. Each pulse of the laser takes less than a second which allows it to treat small areas in minutes and larger areas such as the arms or legs in up to an hour.
Unlike other forms of hair removal, laser hair removal can target very specific areas of the body without damaging the skin in the surrounding areas. It is estimated that close to 90 percent of people will have permanent hair loss after about 3 to 5 sessions with the laser hair technician. However, there are many people that are not good candidates for laser. Anyone that has very light colored, red, or grey hair may not experience good results. This is why it is so important to go to a laser clinic that is reputable and has good reviews. Professional clinics will tell you if you are not well suited for laser and you will not have to waste your money.
What about the side effects of laser? Most people will experience nothing more than a bit of redness for a couple of days on the area that was treated, much like a sunburn. Rarely, some people will develop blisters and most of those people will have a darker complexion. Even more rare, some people could develop permanent scarring and a change of skin color as a result of the laser treatment.
Since the laser utilizes a type of radiation do we need to be concerned with that? You would be exposed to high frequency ionizing radiation when you get a CT scan or X-ray, and that is the worst type of radiation you can get because that can damage your cells. However, according to the FDA, lasers used with hair removal utilize non ionizing radiation so there should not be any long term risk. As of now there is no evidence that the light from the lasers cause long term problems. Regardless, it would probably be good to limit your exposure to these lasers as much as possible and only treat the areas of your body that really cause you grief.
