Introduced about 2 decades back, laser hair removal treatment is now widely accepted by dermatologists as a safe and effective method of removing unwanted hair from small and large areas of the body. Laser therapy is also approved by the US Food and Drug Administration (FDA).
Today, laser treatment is being preferred over other methods of hair removal because of its speed and efficacy. To get effective results and to ensure safety, you should get the laser treatment conduced by a skilled and experienced professional. Laser treatment is highly popular for removal of unwanted body hair from the face, underarms, legs, pubic area, back, chest, abdomen and shoulders.
How does laser therapy work?
In laser hair removal therapy, an intense, pulsating beam of focused laser light energy is passed through the skin targeting dark pigment, called melanin, in hair. The intense heat of laser light burns the hair follicle causing permanent damage and thereby prevents the growth of new hair. Laser does not heat or damage the surrounding skin.
Laser therapy is not a permanent method of hair removal as many people claim it to be. However, it does keep unwanted body at bay for several months and even years altogether.
Comparison with electrolysis
Electrolysis is another popular method of hair removal that has been around for more than a century. Discussed below are differences between laser therapy and electrolysis treatment.
-Method of treatment – Electrolysis is an invasive technique in which a needle penetrates deep through the skin in the hair follicle whilst laser is a non-invasive technique. In this method, only light energy is used for hair removal
-Time taken – Electrolysis consumes more time than laser treatment as it treats single hair follicle at a time. Laser on the other hand, targets dozens of follicles simultaneously and hence takes less time. Small procedures may only require a single session
-Re-treatment – Since electrolysis destroys a follicle permanently, a treated hair follicle is not to be treated again. In case of laser, if a follicle treated with laser light begins to grow hair in due course, you may have to treat the same follicle again
-Effectiveness – The FDA currently allows the term “Permanent Hair Removal” for electrolysis. It is effective on all hair colors unlike laser. On the other hand studies prove that laser hair removal is faster, less painful and more reliable hair removal treatment than electrolysis but is effective for only some hair colors.
