Is At-Home Laser Hair Removal Safe? Here's What Experts Have to Say

Experts break down how to use the devices safely.

Shaving is tiresome, waxing is painful, and laser hair removal is expensive. So it makes that at-home laser hair removal—a method that promises painless, permanent, and affordable hair removal results—is gaining more buzz.

But for a treatment that typically requires an esthetician’s supervision (and thousands of dollars worth of in-office sessions), is it safe to do at home? We tapped Hadley King, MD, board-certified dermatologist, and Adriana Perez-Nakamura, licensed esthetician, founder of Skincare By Adriana to investigate.

What is laser hair removal?

Unlike waxing, which uproots hairs from deep in the follicle, the laser hair removal process targets the dark pigment in your hair follicles, damaging it enough to stunt future growth.

“Laser hair removal treatments emit light of a wavelength that is absorbed by melanin in the root of the hair,” says King. “The light energy is converted to heat, which permanently damages and destroys hair follicles.”

In order to achieve the best results, you’ll want to use the treatment at the first stage of hair growth. “There are three stages of hair growth: anagen (growing phase), catagen (transition phase), and telogen (resting phase),” says Perez-Nakamura. “In order for the laser to be effective, you have to target hair while it’s in the anagen phase. The hair you want to remove will be in each of these phases at different times, so you’re going to need several treatments before you notice results.”

At-Home Laser Hair Removal Vs. In-Office Treatments

According to Perez-Nakamura, at-home handheld laser-hair removal devices are typically marketed as laser devices when they are usually actually IPL. “IPL stands for 'intended pulsed light' and uses light pulses to target melanin in the hair follicle," she says.

While IPL works on the same principles as lasers in that light energy is converted to heat energy (which causes damage to the specific target area), it's very different in that it delivers many wavelengths (or colors) in each pulse of light instead of just one wavelength. Professional laser treatment is a more selective process, and therefore the very high energy will focus on the hair follicle rather than surrounding skin.

In other words, IPL treatments are typically weaker and require more treatments than your standard in-office procedure. “At-home devices use lower energy settings so that they are safe to use on your own,” says Dr. King. “For in-office laser treatments, you should expect 5 to 7 sessions, spaced at least 4 weeks apart. After that, you should get a maintenance treatment once or twice a year. When using at-home laser treatments, more treatments will be necessary because the energy from your at-home device uses a lower energy.”

Also, keep in mind that while long-lasting, at-home laser hair removal treatments aren’t considered to be permanent. “The results can last anywhere from a few months to a few years,” says Perez-Nakamura. “You will likely need additional treatments later on to maintain your results.”

Is at-home laser hair removal safe?

Short answer: yes. “At-home laser hair removal is typically safe as long—if you follow directions and use caution to avoid burning,” says Dr. King. However, it’s also important to note that at-home laser hair removal isn’t for everyone.

According to Dr. King, those with a darker complexion have an increased chance of blistering and burning. “Because these devices target melanin (the pigment in our skin and hair), the best candidates for at-home laser hair removal will be those with light skin and dark hair,” she says. “That's the ideal set up so that the device can target the hair without damaging the skin. Darker skin will increase the risk of burning, and lighter hair can decrease the effectiveness.”

Additionally, Perez-Nakamura says there are certain factors that mean you shouldn’t do laser hair removal at all, i.e. if you’re on certain medications (consult with your doctor first), pregnant, or using retinoids or on Accutane.

Since professional laser hair removal devices have more settings, they’re usually more customizable to fit an individual’s skin type. And while experts at an office will ask all the right questions and take precautionary measures to make sure there are no adverse effects (for example, professional laser treatments can be adjusted to work with darker skin tones), you're more at risk if you do it yourself. That’s why in-office treatments are preferable, but if you choose to do it at home, it’s always best to speak with a medical professional to make sure you’re using the right device for you.

In the case of the beauty industry, the term "clean" is usually understood to mean that the product is free of parabens and formaldehyde-releasing agents -- but there's no court, other than that of public opinion, that could punish a company for claiming to be clean while using these or other potentially harmful chemicals.
