Laser hair removal is a procedure by which hair is removed from the body by utilizing a long pulse laser. Lasers are developed and designed from years of research. The laser parameters are carefully defined by studying the anatomy of the hair follicle and precisely matching the laser light and pulse duration to the follicle size, depth and location to inhibit the re-growth of the hair.
Laser hair removal is performed by a specially-trained laser specialist or a doctor depending on where you go, who distributes the light of a long pulse laser onto the skin. The laser works by disabling hairs that are in their active growth cycle at the time of treatment. Since other hairs will enter their growth cycle at different times, several treatments are necessary to disable all of the follicles in a given area.
Laser works best on pale skin and dark coarse hair. The closer you are to this combination (i.e. the lighter the skin and the more coarse and dark the hair), the better the results will generally be. Alexandrite long pulse and diode types of lasers work best on light-colored skin. Nd:YAG long pulse lasers are better and safer on darker skin (skin types IV and darker ? see Question #12 below to determine your skin type). Since laser works by being attracted to and targeting the dark pigment, using an alexandrite or a diode laser on darker skin can result in skin burning or loss of skin pigment (hypo-pigmentation). Long pulse Nd:YAG lasers were created to cater to dark-skinned patients, so they are safer on the skin at settings that actually affect the hair than alexandrite and diode lasers.
When choosing your hair removal options, select an environment whose main priorities are your safety, health, and results.
The general opinion is that laser hair removal is permanent, and the Food and Drug Administration approved it as ?permanent reduction,? but doesn?t work on everyone. Generally, this means that you shouldn?t expect laser to remove every single hair from an area. Most people need to follow up with electrolysis treatments for any remaining hairs for complete clearance as hair becomes too fine for laser to target and you reach diminishing returns. Most will also need touch-up treatments 1-2 times a year after the initial set of treatments for any new growth your body develops with age
