Procedure of Laser Hair Removal
After consulting with the doctor, the patient’s body where the hair wants to be removed will be cleaned. Furthermore, if the patient has sensitive skin, a gel can be applied to reduce irritation. Patients, doctors and everyone in the room are required to wear protective goggles to protect the eyes from exposure to laser light.
Parts of the body that hairs can be removed include the face, bikini area, arms, chin, legs, thighs, and back. The duration of treatment depends on the dimensions of the body parts. The larger the treated area, the longer the treatment process. Vice versa, a smaller area requires a shorter treatment time.
In contrast to intense pulsed light (IPL) which uses polychromatic light, laser hair removal emits monochromatic light so that it can focus more on a specific area. Although both can remove hair effectively, laser hair removal is capable of providing more permanent results than IPL.
How Laser Hair Removal Works?
After the body area is cleaned, the doctor will shoot a laser beam which is then absorbed by the pigments in the hair. The light energy that is converted to heat damages the hair follicles. Damaged hair follicles will prevent hair growth for a relatively long period of time. Laser drawn onto hair pigments makes them evaporate instantly. The hair that evaporates from the laser energy forms a puff of smoke and smells like sulfur.
Patients with dark hair and light skin are ideal candidates for laser hair removal because the pigments in the hair attract the laser light. In contrast, people who have dark skin need to be treated with a special type of laser.
How laser hair removal feels on one’s body parts? During treatment, the patient will not feel pain. Each patient feels differently depending on several factors such as skin sensitivity for example. They may feel a light pinching sensation. Some patients also feel a sensation like sunburn.
Most hair removal tools use one specific type of wavelength. The most common ones are 755nm, 808nm, and 1064nm. One laser machine that is popular in medical aesthetics is Alma laser hair removal device.
The Super Hair Removal (SHR) developed by Alma takes advantage of high-repetition pulses that are sent deep into the dermis. Not only that, the Alma engine is also equipped with a cooling system that prevents pain during the session.
