Laser Hair Removal: How does it work? We are fortunate to have these days for laser hair removal for unwanted hair. In recent years, people had to suffer through waxing or plucking to have hair-free skin, but laser treatment is safe, effective and fast.
Each hair is produced by a hair root or follicle, and some follicles produce more than a hair. The laser light is absorbed by the pigment (melanin) in hair and hair follicles, causing the follicle to close. The light penetrates the surface layer of the skin (the epithelium) to reach the second layer, the dermis, where there are many vital skin structures such as sweat and sebaceous glands, blood vessels, and a matrix of collagen and elastin, which maintains the skin's surface to hold on. Some skin rejuvenation procedures offered these days by dermatologists aesthetic are based on stimulation of the aging of the skin to produce more collagen.
Hair follicles are also in the dermis. Hair grows in a cycle of three phases: a growth phase followed by an intermediate phase or a phase transition and load shedding in the absence of new hair is produced. When you have a procedure for laser hair removal, the laser can not close the follicles are in growth phase.
Therefore, repeated treatments are necessary. As the follicles enter and leave their phases, each treatment can affect all people in the growth phase until you are satisfied with the degree of hair removal.
The body parts that can be treated
Laser hair removal can run on any surface and usually works on the armpits, chin, upper lip, legs and bikini line. In men, it is also used for the chest and upper back.
Am I a good candidate for laser hair removal?
Because laser hair removal works by the laser light is absorbed by the pigment, your application is determined by the hair and skin color and contrast them.
If you have black hair, dark brown or dark red and pale skin, you would be an excellent candidate. Because the laser light will be absorbed by the pigment of the hair, leaving the affected skin.
If you have blond, gray, hair light brown or light reddish-skinned, you probably would not be a good candidate. Your dermatologist may decide, depending on the degree of contrast between the hair and skin colors.
If you have dark skin and hair black or colored, you would not be a good candidate. The laser light is absorbed by the pigment of the skin and hair would leave unaffected. If your skin is blackened by the sun, you might be a better candidate, if you wait until it fades a little.
