How Does Laser Hair Removal Work?

By Edited Nov 1, 2016 0 0

If you suffer from unwanted body or facial hair, you may want to consider laser hair removal. This procedure is a safe and effective way to eradicate unsightly hair and can be used on nearly every part of the human body. Your treating doctor sends laser pulses into the skin using a beam of light. This light turns into heat as it enters the skin and deactivated the growth of the follicle. Once deadened, the hair ceases to grow and, after time, results in smoother skin. While the laser is relatively painless and feels like a rubber band snapping against your skin, the laser is highly effective, with some of the newer laser types covering an area about the size of a nickel with every pulse.

How Does Laser Hair Removal Work?
Effective results from these treatments depend in part on the timing of the sessions. Because the laser deactivated only those hairs that are in a growth phase, not every follicle is affected during each treatment. It is estimated that half of the hairs in the targeted area are made dormant during each appointment. It is recommended that sessions be timed 4-6 weeks apart, allowing for the remaining hairs to be treated as they, too, enter into the growth phase. While most patients enjoy near-permanent hair removal after several treatments, there is a possibility of future growth. Follow-up visits years later usually take care of this problem.

While the laser beams that produce these dramatic results are powerful and highly complex, the actual pain experienced during the procedure is minimal. Prior to beginning the treatment the doctor will apply a cooling gel to the skin, allowing the laser to target the follicle's melanin while protecting the patient from any harmful effects.

The best candidates for laser hair removal are those with a high degree of melanin in their hair. Melanin is what gives the follicle a dark color so the higher concentration of melanin, the darker the hair. Although, in the past, those with lighter or blonder hair couldn't enjoy the best results from laser treatments, new developments in laser technology are making these procedures available to those with fairer hair as well as darker haired individuals.

It is not only the tone of the hair but the skin as well that effects the outcome of laser removal. Melanin is also responsible for the color of one's skin so it stands to reason that fairer skinned individuals don't get the same results as their darker skinned counterparts. As is the case with lighter hair, new types of lasers are making it possible for lighter skinned patients to reap the benefits of laser technology.

Luckily for those individuals who seek a safe and longer-lasting form of hair removal, there are numerous types of lasers that can be used on all types of skin colors and many different types of hair follicles. Gone are the days when a small portion of those effected by unwanted body hair could reap the benefits of laser hair removal. Innovations have also allowed for longer lasting results. Although these lasers may have different qualities they all work in the same way to improve people's lives through the use of new technology.
