BY: Groupon Editors |Mar 19, 2020

How does laser hair removal work? It may not be the most intuitive of hair-removal treatments. With shaving, plucking, waxing, or threading, the method is pretty much in the name. But to laser hair? What does that even mean? And if lasers are involved, will it hurt? With that kind of technology, how much will it cost? Finally, will it be worth all the effort?

Never fear! We're here to answer your most pressing LHR questions and help you better understand what to expect when you decide to bid fuzz farewell.

How does laser hair removal work?

Laser hair removal is a noninvasive treatment in which concentrated beams of laser light target the pigment in a hair follicle. The pigment absorbs the light, causing the follicle itself to be damaged. This damage inhibits the hair's ability to grow back. Read more about the different types of laser-hair-removal lasers to decide which is best for you.

Laser hair removal can cost anywhere from several hundred to several thousand dollars per treatment area, and most areas require multiple treatments for the best results. If cost is a concern, check out our deals on laser hair removal, which is typically offered at up to 90% off.

Does laser hair removal hurt?

Typically, experts say laser hair removal hurts about as much as being snapped by a rubber band. In other words, it may be uncomfortable, but not unbearable. The amount of pain you feel will also be largely based on your own personal pain tolerance, as well as the area of the body being lasered. Sensitive areas, such as the areolae or bikini line, may be more tender. Numbing creams may be provided by your technician, by request, and you can also take a painkiller, such as ibuprofen, beforehand.

We delved deeper into what laser hair removal feels like by polling med-staff staff, as well as one of our editors. Here's a firsthand account on the truth about laser-hair-removal pain.

How many sessions will I need?

Depending on the laser and your skin and hair type, you may need between 5 and 12 sessions, spaced four to six weeks apart. The laser is effective only on hairs going through a growth cycle—and not all hairs in an area grow at the same time. Once the initial sessions are up, you may have to go back for regular maintenance treatments.

Is laser hair removal permanent?

If you've really decided to ditch the razor for good, you may be wondering: how long does laser hair removal last? Results vary from person to person, and for most people, laser hair removal slows hair growth considerably, and also makes it less noticeable.

However, laser hair removal is often marketed as a permanent hair-removal treatment, but most people eventually need touch-ups. After their initial series of treatments, clients typically have to return once a year—sometimes more, sometimes less.

Because results vary according to skin tone, hair color, and the type of treatment used, it is important to find the ideal laser for your needs to get 

Is laser hair removal safe?

Laser-hair-removal treatments are generally regarded as very safe, though some minor side effects such as redness and irritation are possible. If you're worried about posttreatment discomfort, your technician may be able to provide a numbing balm for use afterward. Additionally, you may be asked to avoid the sun for a short time following treatment and to use sunscreen liberally.

Do I need to do anything special before or between treatments?

It's best to avoid anything that might stress the hair or skin: shaving, waxing, even exposure to the sun. Read more about before and aftercare for laser hair removal treatments.
