Laser Hair Removal and Recovery
Laser hair removal uses a concentrated beam of light to remove unwanted hair. The intensity of the laser beam destroys hair follicles, preventing hair from growing again from that follicle. Laser hair removal can be performed by doctors or specially trained technicians. Because complete hair removal in the desired area often takes several sessions, the procedure can become costly, particularly if hair is being removed from a large area. Does this Spark an idea?

Laser Types
-
The Alexandrite Laser is the fastest laser and is used to treat large areas of the body. It works best on patients with light or olive complexions. The Ruby Laser is effective in removing light or fine hair, while the Diode Laser is most effective on people with darker skin. The Long Pulse Nd:Yag laser is effective for all skin types, but may cause more discomfort than other types of lasers.
Considerations
-
Laser hair removal works best on people who have black or brown hair and light skin. Laser treatment can be used on people with darker skin, but results may not be as dramatic because darker skin tends to absorb the light from the laser beam before it can reach the hair follicles. Lasers cannot remove blond, white, light red or light brown hair.

Preparation
-
Before the procedure, you will meet with your doctor or technician to discuss your medical history and the risks, benefits and success rates for the procedure. In most cases, you won't be able to have laser hair removal if you have a tan, because a tan will increase discoloration and blistering following the treatment. Your doctor or clinician may ask you to shave the area to be treated a few days before your treatment is scheduled.
The Procedure
-
During the procedure, the doctor or technician holds the laser instrument against your skin and then activates the laser. You will wear goggles to prevent your eyes from any damage from exposure to the laser beam. Because laser treatment can sting, you will be provided with a topical anesthetic to prevent discomfort during the procedure. Treatment ranges from several minutes to several hours, depending on the size of the area to be treated.
Concerns
-
Laser treatment may darken or lighten the skin in the treated area. This pigment change may be temporary or permanent. In rare cases, scarring, blistering or skin texture changes may occur. There may be some scabbing of the treated area, although this is usually only a temporary condition. Additional treatments may be needed to remove hair that has regrown or was resistant to the initial treatment.
Recovery
-
Redness and swelling may occur for a few hours after laser hair removal, and you may experience a stinging sensation for one or two days following treatment. If the treated area develops a crust, your doctor or technician may suggest that you keep this area moist until it heals. You should avoid sun exposure for a few weeks following treatment and be sure to use sunscreen on the affected area. Sweating should be avoided for the first 24 hours because it can increase skin irritation.
