Laser Hair Removal Technologies
Laser Hair Removal is by far the most effective and quick treatment for the removal of unwanted hair today. Other methods like thermolysis, electrolysis and blend (which is a blend of both thermolysis and electrolysis) are far more time consuming, painful, require more sessions and in effect cost much more. Hence if you feel the need to get unwanted hair removed or reduced permanently, a Laser Hair Removal Clinic is where you should be headed.
A visit to a qualified dermatologist is the first step towards laser hair removal. The dermatologist determines your skin type and its pigmentation. Types of skin and hair color are the primary elements on which the intensity and result of laser treatment is based. Though the system is most effective for persons who have light skin and dark hair, it can be used on persons with darker skin too.
The procedure for laser treatment is simple but should be performed by experienced professionals. The patient is made to wear eye protection consisting of an opaque covering or goggles. The area to be treated is shaved and a coolant is applied liberally as the laser is activated. The size or the area to be treated will determine the cost and the number of laser pulses required. The laser energy is absorbed by the pigment in the hair follicle. A percentage of the follicles are instantaneously and permanently disabled with each treatment. The number of laser hair removal sessions required is dependent on many factors such as thickness of hair, skin color, sensitivity etc. Usually thicker hair are more effectively and quickly removed compared to finer hair. No anesthesia is generally used.
Laser treatment may cause redness in the area where therapy has been performed. At times, the affected skin darkens in color. However, these changes are short lived and the skin recuperates slowly. If the redness or rashes persist, visit your doctor again.
Following is a detailed explanation of the various laser hair removal technologies available today. Choose the one that suits your skin the best.
