Benefits of Laser Hair Removal

Lasers are useful for removing unwanted hair from the face, leg, chin, back, arm, underarm, bikini line, and other areas.

Benefits of laser hair removal include:

Precision. Lasers can selectively target dark, coarse hairs while leaving the surrounding skin undamaged.

Speed. 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.

How to 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.

If you are planning on undergoing laser hair removal, you should limit plucking, waxing, and electrolysis for six weeks before treatment. That’s because the laser targets the hairs’ roots, which are temporarily removed by waxing or plucking.

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.

What you can expect

Laser hair removal usually requires two to six treatments. The interval between treatments will vary depending on the location. On areas where hair grows quickly, such as the upper lip, the treatment might be repeated in four to eight weeks. On areas of slow hair growth, such as the back, the treatment might be every 12 to 16 weeks.

For each treatment you’ll wear special goggles to protect your eyes from the laser beam. An assistant might shave the site again if necessary. The doctor might apply a topical anesthetic to your skin to reduce any discomfort during treatment.

Results

Hairs do not fall out immediately, but you will shed them over a period of days to weeks. This may look like continued hair growth. The repeated treatments are usually necessary because hair growth and loss naturally occur in a cycle, and laser treatment works best with hair follicles in the new-growth stage.

Results vary significantly and are difficult to predict. Most people experience hair removal that lasts several months, and it might last for years. But laser hair removal doesn’t guarantee permanent hair removal. When hair regrows, it’s usually finer and lighter in color.

You might need maintenance laser treatments for long-term hair reduction.
