What is laser hair removal? from skeily's blog
Laser hair removal is the process of removing excess hair by exposure to laser pulses that destroy the hair follicle. The efficacy of laser hair removal is now generally accepted in the dermatology community, and laser hair removal is widely practiced in clinics, even in homes that use devices designed and priced for consumer self-treatment. A number of reviews of laser hair removal machine, safety and efficacy have been published in the dermatology literature.
How many times does hair removal take?
Hair grows in several stages (early anagen, telogen, mid-hair growth), and the laser only affects the currently active hair follicles (early hair growth). Therefore, several meetings are required to kill the hair during all stages of growth.
It has been shown that a variety of treatments depending on hair type and skin tone can reduce hair for a long period of time. Most patients require at least seven treatments. Current parameters vary from device to device, but manufacturers and clinicians typically recommend waiting three to eight weeks between meetings, depending on the area being treated. The number of sessions depends on various parameters, including the area of the body being treated, skin tone, rough hair, causes of hirsutism, and gender. The rough black hair on light skin is the easiest to treat. Certain areas (especially male faces) may require more treatment to achieve the desired results.
Typically, the shedding of the treated hair takes about two to three weeks. These hairs should be allowed to fall off on their own and should not be manipulated by the patient for some reason, mainly to avoid infection. Pulling the hair over a period of time may be more painful and counteract the effects of the treatment.
What are the side effects of laser hair removal?
Some normal side effects may occur after laser hair removal treatment, including itching, pink skin, redness, swelling around the treatment area or swelling of the follicles (follicular edema). These side effects rarely last more than two or three days. The two most common serious side effects are acne and skin discoloration.
A certain degree of pain should also be expected during treatment. Anesthesia cream is available in most clinics and sometimes at an additional cost. There is some numbing paste on the counter. A strong anesthetic cream must be avoided in the large skin area of a treatment because it can seriously damage or even kill the patient. Typically, the cream should be administered about 30 minutes prior to surgery. The icing area after treatment helps to alleviate side effects more quickly. Ibrahimi and Kilmer report on a new diode cell phone device with large spot size and vacuum-assisted aspiration to reduce the pain associated with laser treatment.
