First, the lowdown on lasers and how they work: They beam intense light at the follicle, causing permanent damage so hair no longer grows. But because they work by targeting the pigment in the hair—it’s the contrast between dark hair and lighter skin that helps the laser focus on its bullseye—the ideal candidate has traditionally been someone with fair skin and dark hair.
For that reason, laser hair removal for dark skin has been a gamble: Devices weren’t sophisticated enough to completely distinguish between the pigment in brown or Black skin and dark hair, meaning that they could potentially cause dark and light spots, blisters, and even scarring in the skin surrounding the follicle, says Robyn Gmyrek, M.D., of Union Square Laser Dermatology in NYC. But now there are smarter lasers that can be used in a much more precise—and safe—way, making getting rid of unwanted fuzz a reality for a wider range of skin tones. Here’s how to get it right.
The Best Lasers for Dark Skin
The first and most important thing you need to know is how Nd:YAG and diode lasers work for dark skin and dark hair. In recent years the Nd:YAG (or just YAG) has become increasingly popular. “The wavelength of this laser goes deeper into the skin than a diode,” says Gmyrek. “So it more successfully bypasses the pigmentation present in the skin.” Because the YAG basically bypasses the melanin in your skin, it’s the safest option for medium to dark skin. It’s one of two lasers Shobha Tummala, founder and CEO of Shobha hair removal, offers in her salons. (She’ll also use it for fair-skinned clients who have recently gotten a tan.)
But the diode has its perks, even though it might be more complicated for anyone above a 4 on the Fitzpatrick scale (the standard measure of skin type used by dermatologists, with 1 being the lightest and most sun-sensitive and 6 being the darkest). “In patients with dark skin, the diode laser energy has to be delivered in a slower manner per pulse, leaving more time for skin to cool,” says Gmyrek. “It also has an instant cooling device that protects pigment from overheating and being damaged.” The Lumenis LightSheer laser, one of the most popular diode lasers out there, even has a suction mechanism to distract your attention from the pain. “I would overall say that it’s the least painful,” says Estee Williams, M.D., a dermatologist in New York City.
Risks of Laser Hair Removal on Dark Skin
You’ll want to minimize the chances that you’ll develop the most common laser-related side effects for dark or Black skin: hyperpigmentation, or dark spots, and hypopigmentation, in which the skin pigment lightens. According to Williams, hypopigmentation can be harder to treat (although Gmyrek notes that it can sometimes resolve on its own), so ask your laser removal expert to do a test patch if you think you might be prone to it—just to be on the safe side.
Cost of Laser Hair Removal
Expect to need at least six sessions. Although darker skin can sometimes require more treatments than fair, “everyone’s different,” says Tummala. The downside is that the cost can add up quickly, as many providers charge by the session. According to the American Society of Plastic Surgeons’s 2017 stats, the average cost per session was $293—but it varies wildly depending on what part of the body you’re targeting. (Generally, the larger the area, the higher the price.)
At many practices, there’s no difference in cost between the YAG and diode. Some research shows that the diode might be slightly more effective at actually removing hair on brown or Black skin—it could also be worthwhile if you’re closer to 3 on the Fitzpatrick scale and have a low pain tolerance. But Gmyrek believes that the Nd:YAG is the safest bet overall for laser hair removal for dark skin.
How to Prepare for Your Laser Hair Treatment
Now is not—we repeat, not—the time to get a coupon through a discount site. The provider (and their expertise) matters. “I was willing to pay a premium and see a professional with great reviews,” says Marlene, 28, who had the treatment done on her underarms. A pro who has extensive experience with laser hair removal for dark skin is essential.
Not only should you expect the same type of screening and forms you would from any medical professional, it should also include your ethnicity, because different ethnicities—regardless of skin tone—react differently to lasers. Your skin may appear to be a 3 or 4 on the Fitzpatrick scale, but if you’re, say, Latinx or Asian, it could react to the laser as a 6 would.
Once you’re scheduled, coddle your skin. Stop using skin care products with harsh ingredients, including glycolic and salicylic acids, benzoyl peroxide, and any retinoids (including tretinoin and adapalene), at least five days before your treatment. “These can all make your skin more sensitive to the laser energy,” says Gmyrek.
Go full vampire and keep out of the sun—or at the very least, use proper protection. (That’s broad-spectrum SPF 30 or more; tinted moisturizer or foundation with SPF doesn’t count.) A tan equals more pigment, which can spur a different (and potentially dangerous) reaction to the laser. “If you’re even slightly tanned, inform the laser provider so that the treatment energy can be lowered or the treatment rescheduled,” says Gmyrek.
Caring for Dark Skin After Laser Hair Removal
Side effects can still happen—but you’ve got options. “For irritation or redness, hydrocortisone can help to resolve the inflammation,” says Gmyrek. “For an acne-like eruption, or folliculitis, use topical antibiotics.” For any hyperpigmentation, try a topical cream for dark spots, which your derm can prescribe. “It’ll help normalize the skin color,” says Gmyrek.
But many who once felt a need to shave daily say the minimal upkeep has been well worth it. “My overall experience was great,” says Marlene. The best part? She didn’t experience burns or pigmentation problems, proving just how far laser hair removal for dark skin has come.
