Laser hair removal can permanently reduce the amount of hair on your body. Laser hair removal uses specialized equipment that emits wavelengths of laser light that target the melanin in your hair. By using the melanin, a skin pigment, for guidance, the laser is able to transmit energy into the hair follicle, destroying its ability to grow new hair strands. Although laser hair removal is convenient, it can be pricey and requires multiple treatments for best results. Laser treatments also have potentially dangerous risks, making it important to fully understand the procedure before proceeding.
Burn
One possible danger of laser hair removal surgery is the development of a skin burn. Lasers impart high levels of energy into the skin, which creates heat. Typically, a small burst of cool liquid spray accompanies each laser treatment to help protect the skin from burning, according to the American Academy of Dermatology. However, burns are still possible. Your chances of burns can increase if you have spent a substantial amount of unprotected time in the sun before your treatment, or spend time unprotected in the sun immediately after your treatment.
Allergic Reaction
Laser hair removal treatments can create a pain similar to being snapped with a rubber band. To lessen this pain, some treatment centers use a local anesthetic to numb the treatment area. The Food and Drug Administration has received reports of serious and life-threatening side effects from the overuse of skin-numbing medications during laser hair removal treatments. If you are allergic to anesthetics, side effects can range from mild skin irritations, such as a rash or itching, to severe reactions, such as difficulty breathing or anaphalaxis.
Skin Discoloration
Skin discoloration, such as hyperpigmentation or hypopigmentation, may also occur during a laser hair removal treatment. This change in color occurs as the laser reacts with the melanin in your skin. Melanin is the substance that gives your skin its pigment. According to the Mayo Clinic, pigment changes are typically temporary, and occur more often in those with darker skin.
Scarring
In rare cases, laser hair removal treatments may also cause scarring on the skin. Scarring occurs when the laser is used incorrectly and damages the surrounding skin tissue. Scarring can be limited by always insuring your hair removal treatment is performed by a licensed and experienced practitioner.
