Laser Hair Removal Procedure
Laser Hair Removal
The use of lasers for hair removal has been studied for a number of years. In this procedure, laser device is consumed by melanin in the hairs base, damaging the follicular epithelium.
Laser techniques focuses on the endogenous chromophore melanin, which is mainly found in the hairs base, with a small amount present in the upper third of the follicular epithelium. When an appropriate way to obtain energy (such as a laser) is directed at the skin, light is primarily consumed in the hairs base melanin. Heat is produced and diffuses to the surrounding follicular epithelium. A identical principle applies to laser device treatments of general lesions, where heat produced after consumption by hemoglobin is transferred from the blood to the general endothelial cells.
Laser techniques are based on the principles of selective photothermolysis: a combination of the appropriate laser device wavelength, pulse duration, and fluence. Wavelengths between approximately 700 and 1000 nanometers (nm) are selectively consumed by melanin; the competing chromophores (oxyhemoglobin and water) absorb less energy at these wavelengths. Determine 2 shows the consumption of different chromophores in the skin. Therefore, any light that operates between 700 and 1000 nm is appropriate for targeting melanin in the hairs base.
There is a difference between long lasting hairs decrease and finish thinning hairs. Complete thinning hairs imply that there are no regrowing hairs. This can be a brief or long lasting phenomenon. The LightSheer Diode Laser usually produces finish but short-term thinning hairs, followed by a partial but long lasting hairs decrease. This is an important distinction to make when setting patient expectations. With this laser device, 100% of the sufferers experienced short-term thinning hairs, while 89% of the sufferers had long lasting hairs decrease at one year follow-up. Of the 11% of sufferers who did not have long-term thinning hairs, most had brown hairs. Because brown hairs contains less melanin than darker.
