Hair Removal
-
The word "laser" is actually an acronym that stands for Light Amplified by Stimulated Emissions of Radiation. One of the most common types of laser treatment is for hair removal. Laser hair removal is used by both women and men alike. Sometimes it is done for aesthetic purposes, and other times it is done for professional reasons. This would be the case if someone was a competitive bodybuilder or swimmer, for example.
In this type of treatment, a beam of laser light is sent down the shaft of the hair into the follicle. This kills it and stops it from growing back again. But this procedure is only effective when the hair is in a growing phase. For this reason, it generally takes up to four treatments to remove all the hair.
Acne Treatment
-
Acne is caused from enlarged sebaceous glands under the skin. A lot of adolescents and even adults suffer from acne and scars that were brought on by it. After trying all kinds of formulas and remedies to no avail, they sometimes end up resorting to laser treatment. This type of treatment is characterized by the emission of a pulsating beam of heat under the skin which shrinks the sebaceous glands, causing the acne to go away.
There are three different types of lasers used in this procedure. Nonablative lasers help to tighten the skin and stimulate collagen growth, which gives skin its tone and elasticity. Erbium lasers emit heat into the water molecules of the skin and are generally used for mild blemishes and wrinkles. Carbon dioxide lasers emit high-energy bursts of light to damaged areas one layer at a time. This is considered one of the best treatments for acne and pimples.
Other Conditions
-
In some situations, laser treatments are used to help relive pain and symptoms of other conditions and disorders. Some of these include joint conditions such as arthritis and tendinitis, lower back pain, migraines and carpal tunnel syndrome. The idea behind this is to emit laser light to injured tissue underneath the skin. When this happens, the body's natural healing potential is increased, the pain is relieved and the possibility for surgery becomes reduced.
