LASER HAIR REMOVAL
ELIMINATE UNWANTED HAIR
Hair removal is one of the most common aesthetic concerns worldwide and affects both men and women.
There are several options available for hair removal, although most are not permanent. Permanent hair removal can only be achieved by applying energy directly to the hair follicle.
How does it work?
Removal or permanent reduction of unwanted hair by laser light is based on the scientific principle of selective photo-thermolysis. When the correct wavelength of laser light is applied to hair in the treatment area, melanin in the hair absorbs the light, which is converted into heat energy. The thermal energy builds up and causes the destruction of hair follicles as well as associated stem cells and dermal papillae, while leaving the surrounding skin undamaged. Some follicles are only damaged and can regrow, so numerous treatments are required to effectively and permanently reduce or eliminate unwanted hair.
To successfully remove unwanted hair by laser treatment, you must apply energy carefully so that hair follicles are damaged but nearby skin and tissues are spared. This can be more or less difficult depending on each patient's individual characteristics such as skin color, hair color and hair thickness. When treating hair with a laser, you can take these characteristics into account by adjusting treatment parameters such as fluency, pulse width and repetition rate. Many devices are limited in their utility because the different parameters cannot be adjusted independently (if at all). Understandably, treatment of darker skin is more challenging due to the higher concentration of melanin in the skin as a competing chromophore; in this case treatment may be too painful or cause burning.
Laser energy is applied to the hair follicle, heat destroys the follicle and prevents future growth.
