How Does Laser Hair Removal For Dark Skin Work?

Laser hair removal for dark skin has been very difficult in the past because of how the lasers work. The laser light is absorbed by the melanin in the hair follicle and the follicle is destroyed so that the hair doesn't grow back. The difficulty arises when it comes to dark or sunburned skin because the laser is unable to distinguish between the skin and hair follicle as the melanin in both absorbs the laser light. Here the melanin itself is in high concentration so the dark skin ends up absorbing the light instead of the hair. As a result the laser is unable to pass through the epidermis to reach the hair follicle. This not only creates problem in achieving the best result but could also cause injury. Darker skin has the potential to burn, develop keloids, or even become discolored.

Many of us are tired and frustrated with unwanted hair growth and the temporary solutions to deal with it. And why shouldn't we be? Anyone having to undergo sticky painful procedures of waxing or the bother of shaving every few days would be in exactly the same position. Most of us really long to have that perfect solution to permanently prevent unwanted hair growth and laser hair removal is the most ideal solution. Although laser hair removal can be a little painful and expensive, it has worked wonders on people with light complexions and dark hair. But what about laser hair removal for dark skinned Asians and African Americans?

Thankfully, there is a solution! Technological advancements mean that there are procedures that can be undertaken to ensure that laser hair removal on darker skin is safe and effective. Methods like cooling the skin that can prevent it from being injured. That can be done with contact cooling, using two sapphire plates or something similar with water running between, or by using a chilled plate, or a spray that is applied to cool through evaporation thus preventing laser from burning the skin. In addition to this, technicians use longer laser wavelengths. The reason for longer laser wavelengths is that melanin in the skin will absorb the short wavelengths, but longer wavelengths can pass through the epidermis to destroy the follicle. Despite the different varieties of lasers available a diode laser or nd:yag laser are best suited when it comes to laser hair removal for dark skin. In the hands of a skilled technician and with the help of modern techniques, people of Asian or African American origin can easily get rid of all their unwanted hair with laser treatment for hair removal.
