Laser hair removal is selective photothermolysis (SPTL) which matches specific wavelengths of light and pulses for a specified duration to obtain the desired effect on a targeted area with minimial effects to the surrounding are. Lasers are able to focus on localized areas by selectively heating dark hairs and melanin of hair growth follicles and not the skin.
Melanin is considered the primary chromophore for all hair removal lasers currently on the market. Melanin occurs naturally in the skin, and gives skin and hair their color. There are two types of melanin in hair. Eumelanin gives hair brown or black color, while pheomelanin gives hair blonde or red color.
Due to the selective absorption of photons of laser light, only black or brown hair can be removed. Laser works best with dark coarse hair. Light skin and dark hair are an ideal combination, being most effective and producing the best results, but new lasers are now able to target dark black hair with some success in patients with dark skin.

Lasers can selectively target dark, coarse hairs while leaving the surrounding skin undamaged.
Each pulse of the laser takes a fraction of a second and can treat many hairs at the same time. The laser can treat an area approximately the size of a quarter every second. Small areas such as the upper lip can be treated in less than a minute, and large areas, such as the back or legs, may take up to an hour.
Ninety percent of patients have permanent hair loss after an average of three to five sessions.
Prepare for Laser Hair Removal
Laser hair removal is more than just ”zapping” unwanted hair. It is a medical procedure that requires training to perform and carries potential risks. Before getting laser hair removal, you should thoroughly check the credentials of the doctor or technician performing the procedure.
You should also avoid sun exposure for six weeks before and after treatment. Sun exposure makes laser hair removal less effective and makes complications after treatment more likely.
Results of Laser Hair Removal
Just before the procedure, your hair that will be undergoing treatment will be trimmed to a few millimeters above the skin surface. The laser equipment will be adjusted according to the color, thickness, and location of your hair being treated as well as your skin color.
Depending on the laser or light source used, you and the technician will need to wear appropriate eye protection. It will also be necessary to protect the outer layers of your skin with a cold gel or special cooling device. This will help the laser light penetrate the skin.
Next, the technician will give a pulse of light to the treatment area and watch the area for several minutes to make sure the best settings were used and to check for bad reactions.
When the procedure is completed, you may be given ice packs, anti-inflammatory creams or lotions, or cold water to ease any discomfort. You may schedule your next treatment four to six weeks later. You’ll get treatments until hair stops growing.
Recovery and Risks
For a day or two afterward, the treated area of your skin will look and feel like it’s sunburned. Cool compresses and moisturizers may help. If your face was treated, you can wear makeup the next day unless your skin is blistering.
Over the next month, your treated hair will fall out. Wear sunscreen for the following month to help prevent temporary changes in the color of the treated skin.
Blisters are rare but are more likely in people with darker complexions. Other potential side effects are swelling, redness, and scarring. Permanent scarring or changes in skin color are rare.
