A growing variety of cosmetic procedures now include laser
technology. Examples include the elimination of pigmented spots, treatment of
vascular lesions, hair reduction, skin resurfacing for acne scar therapy,
and/or wrinkle reduction. Tattoos may also be removed with lasers. Online
retailers provide Cosmetic lasers.
Background
For use in aesthetic procedures, a variety of medical devices utilizing similar technology have received Canadian licensing. These technologies, which all work on the same fundamental principles, include various kinds of lasers, strong pulsed light, and radio-frequency energy.
Lasers produce a concentrated beam of visible or invisible energy or light with a predetermined wavelength that is directed toward a particular kind of tissue in the area of the body that is being treated. The energy beam is absorbed and transformed into heat when it reaches its intended destination. If the operation is carried out correctly, the heat inactivates or kills the target cells without significantly affecting the cells around them.
The melanin in the hair follicle is the target of the used hair removal laser system for hair reduction (or root). The gadget targets and destroys skin cells close to the skin's surface to cure acne scars and reduce wrinkles. The outcomes are comparable to the tightening of the skin brought on by conventional skin resurfacing techniques including chemical peels and mechanical abrasion. The laser's light is focused on the blood vessels to treat vascular lesions like spider veins.
Using the right wavelength causes damage to the vessel wall, which is then absorbed by the body. A similar idea underlies treatments for tattoos and surface imperfections. The selection of the appropriate equipment for a specific treatment, the training and proficiency of the person using the device, and several other factors affect how successful cosmetic laser therapies are.
