If you are looking to remove unwanted hairs, laser hair removal is a possible option for you. Laser hair removal is the second-most popular cosmetic procedure performed in the United States---with Botox injections leading the list, according to the American Society for Dermatologic Surgery, or ASDS. The treatment uses a highly concentrated beam of light, which penetrates and destroys the hair follicle. The U.S. Food and Drug Administration approved the manufacturing of laser surgery equipment for "permanent reduction" in hair, not "permanent removal." Although the FDA has taken great strides to ensure equipment safety, you should consider the side effects prior to treatment.
Skin Irritation
Skin irritation caused from swelling and redness is the most common reported side effect while you undergo laser treatment. Prior to the procedure, you may have a cooling gel or cooling device placed on the laser treatment area. These applications prevent direct heat transference to the skin, which allows the laser to target the hair follicles. Blisters, burns and scarring are rare, but they are after-effects to consider. The ASDS recommends avoiding sun exposure before and immediately after laser treatment for approximately one week to reduce the risk of skin irritation.
Pain
While undergoing treatment, pain can occur either during or post-procedure. Generally, you can use over-the-counter pain relievers, ice, aloe gels or anti-inflammatory creams, or consult with the individual who administered the treatment about your options to reduce pain. Pain from redness and inflammation, also known as perifollicular edema, is normal and common and subsides within 24 hours after treatment, as noted by ASDS.
Skin Pigmentation Changes
The American Academy of Dermatology reports that changes in the color of freckles, moles or tattoos are typical when undergoing laser treatment for hair removal. In rare cases, according to the ASDS, hyperpigmentation and hypopigmentation occurs because of the production of melanin---a substance in the body that controls your skin color. Hyperpigmentation is the increase of melanin, causing the skin's darker appearance, and is typically reversible. However, if hypopigmentation occurs---lightening of the skin caused from a decrease in melanin---the results are generally permanent and irreparable.
