I’m team do-what-you-want when it comes to body hair. Personally, I strive to be hairless. But achieving a smooth finish on every square inch of my skin has been a years-long struggle. I tried shaving, waxing, and even using the best epilators. It wasn’t until I embarked on my laser hair removal journey that I achieved my naked mole rat aspirations.
It took me a little over a year, 16 sessions, and $2,600 out of my pocket, but I can confidently say it was worth every penny and pinch of pain to never have to pick up a razor again. My showers are quicker, ingrown hairs are nonexistent, and my skin is never nicked, scarred, or scraped.
There are at-home laser hair removal devices if that’s more your speed (we’ve thoroughly tested the best of the best), but I’m personally partial to professional, in-office treatments. Whether it’s a dermatologist's office or medspa—I had my laser hair removal done at Skinney Medspa in NYC—an experienced technician and heavy-duty machine zap the melanin of the hair follicle and to prevent continued growth. It's usually a faster process (although it still takes plenty of time), and with a pro at the helm, the risks are fairly minor.
Keep reading to learn everything you need to know about laser hair removal—from how much it hurts to determining whether or not you’re a candidate. I’m sharing my personal experience and insights from Shiela Kassir, MD, co-founder of Kassir Plastic Surgery, and Adriana Martino, licensed aesthetician and co-founder of Skinney Medspa.

What Is Laser Hair Removal?
When it comes to hair removal methods, laser is one of the longest-lasting, most permanent options. It essentially uses a powerful hand-held device with concentrated light energy to zap individual hair follicles, explains Dr. Kassir. “This light gets absorbed by the hair follicles and damages them, preventing future hair growth. Over time, you’ll notice smoother, hair-free skin,” she adds. Laser hair removal can also be done nearly anywhere on the body—from pits and nether region to face and legs.
The catch: there are different types of lasers on the market, some better suited to your particular skin type and tone than others. The Alexandrite, YAG, and Diode laser are popular options, but it’s always worthwhile to inquire which device will be responsible for your hair removal. “The 1064 YAG is suitable for most all skin types—including darker skin tones, whereas an Alexandrite is for lighter skin types, and a Broadband laser is good for most all skin types except very dark skin,” adds Martino. While the YAG has more advanced technology and can effectively treat darker skin tones, the other lasers struggle to identify the difference between melanin in the hair and melanin in the skin, meaning those with dark skin and dark hair run a higher risk of burning or skin damage.
What Are the Benefits of Laser Hair Removal?
Laser hair removal offers a long-term solution to hair removal that you won’t find with other options like shaving or waxing. “After six to eight sessions, you can permanently reduce at least 80 percent of unwanted hair,” explains Martino. It’s also great for reducing ingrown hairs that can come with other hair removal methods, adds Dr. Kassir.
Because laser hair removal slows and often stops hair growth over time, stubble and irritation are also substantially reduced. Even when hair does come back (it’s rare to reach 100 percent removal), it’s finer, thinner, and lighter.
Are There Risks to Laser Hair Removal?
Generally speaking, laser hair removal is very safe. But, as with any light energy treatment, there are risks involved. “Common side effects include temporary redness, swelling, or mild irritation in the treated area,” says Dr. Kassir. “In rare cases, people may experience burns, scarring, or changes in skin color, especially if the wrong laser is used for their skin tone.” The latter is a higher risk for those with dark skin tones.
With that in mind, it’s particularly important to have laser hair removal done by a certified professional with experience working with all hair types and skin tones. If your doctor or medspa doesn’t have the right laser for you, look elsewhere.
Am I a Candidate for Laser Hair Removal?
“Laser hair removal works best for people with light skin and dark hair because the laser targets the pigment in the hair,” explains Dr. Kassir. Unfortunately, the treatment will not be effective for those with light blonde, gray, white, or red hair, as there’s not enough pigment for the laser to target.
Those with dark skin tones do run a higher risk of scarring and hyperpigmentation with laser hair removal, but thanks to new technology—like the Nd:YAG laser—it is considered safe.
How to Prep for Laser Hair Removal
I’ve gotten ready for my laser hair removal treatments a grand total of 16 times, so you could say I’m an expert. First, you want to ensure you’re not using any antibiotics, steroids, or body retinols during the two weeks leading up to your appointment. They can not only make your skin more sensitive to the light, but also cause unwanted extra pain. In the same vein, “avoid waxing, plucking, or bleaching the area, since these methods remove hair from the root and make the laser less effective,” explains Dr. Kassir.
A day or two before your appointment, you’ll also want to give any areas being treated a fresh shave, says Martino. “Then, we can actually treat the hair follicles under your skin.” If you miss a spot—don’t worry; your technician will have a razor on hand for any touch-ups.
What to Expect During Your Laser Hair Removal Appointment
Allow me to walk you through a laser hair removal appointment. I check in at the front desk and am escorted into a private room. Because I get my underarm and Brazilian area treated, I change into a robe, put on a disposable bra, and pop on some funky sunglasses designed to protect my eyes from the light energy device. Once I’m ready to go, my technician walks in and powers up the laser.

She’ll apply a conductive gel to the area before stamping the laser on squares of my skin. Typically, she’ll do two passes, which occasionally require me to get into some interesting, legs-in-the-air positions (you’ll know what I’m talking about if you get a bikini or Brazilian laser). “Sessions can last anywhere from 15 minutes to an hour, depending on the size of the area being treated,” says Dr. Kassir.
Does Laser Hair Removal Hurt?
While everyone has a different pain tolerance, laser hair removal shouldn’t hurt too badly. The sensation is similar to a rubber band snap mixed with mild heat. I don’t need numbing cream, but most offices will offer it as an option if you find the treatment too spicy. “Dark, thick hair under the arms and the bikini area can be particularly sensitive, especially if you suffer from ingrown hairs,” says Martino. “Still, it’s much less painful than waxing and should get easier and easier with every session.”
Even better news: laser hair removal machines are equipped with customizable heat and energy settings. Depending on your pain threshold, your technician can dial down or dial up the power—and, therefore, the pain.
Do I Need to Do Anything After Laser Hair Removal?
I wouldn’t recommend running to the gym or jumping in a scorching hot shower directly after your laser hair removal appointment. Otherwise, you should be able to resume normal daily activities or head back to the office. The big takeaway: “It’s important to avoid direct sun exposure for a couple of weeks and make sure you use sunscreen on the treated areas,” explains Dr. Kassir. If you do tan immediately following your laser hair removal, you risk hyperpigmentation.
For those experiencing irritation or sensitization, Martino suggests applying a calming cream with aloe vera or a thin layer of hydrocortisone.
How Much Does Laser Hair Removal Cost?
The cost can vary depending on the area you’re treating, how many sessions you need, and where you live — bigger cities tend to have higher prices. “Generally, you’re looking at anywhere from $150 to $500 per session. Larger areas like the legs or back will cost more, while smaller areas like the upper lip tend to be on the lower end of the scale,” says Dr. Kassir.
Most doctor’s offices and medspas will offer discount deals and bundles if you buy a pack of sessions or schedule multiple areas at once. For example, I spent roughly $1300 on an under-arm and Brazilian eight-session bundle, which netted out to roughly $160 per treatment.
How Many Sessions of Laser Hair Removal Do I Need?
If you’re a prime candidate (light skin, dark hair), you should see outstanding results within six to eight sessions, which are spaced four to six weeks apart. If you’re a less-than-ideal candidate (light skin, light hair, or dark skin, dark hair), you’ll likely need more sessions to achieve the same results.
While I noticed my hair was softer, finer, and less prevalent after four sessions, I wasn’t satisfied until I completed 16 sessions. Now, I can go months without shaving. I'll occasionally grab my razor for a quick touchup before a big event, but the need is very sparing.
Can You Do Laser Hair Removal At Home?
Yes—you can do laser hair removal at home. But there’s a caveat: they aren’t as powerful as their professional counterparts and, therefore, won’t be as effective. “While they can work overtime, they tend to be slower and less effective, especially for larger areas or certain skin and hair types,” says Dr. Kassir. For example, no at-home laser hair removal device is suitable or safe for darker skin tones — at least not yet.
