An "IPL photofacial" sounds like a facial with a light show. It isn't. Intense pulsed light is a heat-based treatment that works by damaging targets in the skin on purpose, and the same physics that clears a sun spot can burn the skin around it. Whether IPL is a good choice for you depends on what you're treating, which device is used, how it's set, who is holding the handpiece, and your skin tone.
This guide covers what IPL is, what IPL devices are cleared to treat, what the research does and doesn't show, why people with darker skin need to be especially careful, and how the rules on who may operate these devices differ from state to state.
What IPL actually is
IPL is not a laser. A laser emits a single wavelength of light. An IPL device uses a flashlamp and filters to emit a broad band of wavelengths at once. A 2010 review in Lasers in Surgery and Medicine (Babilas and colleagues, PubMed 20166155) describes IPL devices as using "flashlamps and bandpass filters to emit polychromatic incoherent high-intensity pulsed light." Like lasers, the authors note, IPL works by "a more or less selective thermal damage of the target."
In plain terms, the light is absorbed by something with color, such as the pigment in a brown spot, the blood in a small vessel, or the pigment in a hair follicle. That target heats up and is damaged. Filters on the handpiece cut off parts of the spectrum so the operator can aim at different targets.
The key word is selective. The light doesn't know the difference between pigment in a sun spot and pigment in the surrounding skin. When the surrounding skin also holds a lot of pigment, it absorbs energy too. That's the root of the darker-skin problem covered below.
What "FDA-cleared" means for IPL
IPL devices are medical devices, and most reach the U.S. market through FDA's 510(k) process. A 510(k) clearance means FDA found the device "substantially equivalent" to a device already on the market. It's not the same as FDA approval of a drug, and it covers only the specific device and the uses listed in its clearance.
A recent example shows how this works. On June 12, 2026, FDA cleared an IPL system made by Sanhe LEFIS Electronics under 510(k) number K261204. The FDA clearance letter and summary list:
•Regulatory class: Class II.
•Product code: ONF, a "powered light based non-laser surgical instrument with thermal effect."
•Regulation: 21 CFR 878.4810, the regulation for laser surgical instruments used in general and plastic surgery and dermatology. IPL is regulated under this laser regulation even though it isn't a laser.
•Type of use: prescription use.
•Cleared indications: "permanent hair reduction, treatment of pigmented lesions, moderate inflammatory acne vulgaris, ephelides and vascular lesions." Ephelides are freckles.
•Environment of use: a healthcare facility or hospital.
That's one device. Other IPL systems have their own clearances with their own indications, and those lists aren't identical. If a provider tells you their IPL is "FDA-approved," it's fair to ask which device it is and what it's cleared to treat. You can look up any clearance in the FDA 510(k) database by device name or manufacturer.
What people use IPL for
The cleared indications above map onto the most common reasons people book an IPL session:
•Sun spots and freckles. These are the "pigmented lesions" and "ephelides" in the clearance language.
•Redness and small visible blood vessels. These fall under "vascular lesions."
•Unwanted hair. IPL is used for "permanent hair reduction." The comparison table in the same FDA summary describes that as a "long-term stable reduction in number of hairs re-growing" after a treatment regimen, which is not the same as permanent removal of every hair.
•Inflammatory acne. Some devices are cleared for moderate inflammatory acne.
How strong is the evidence?
The Babilas review summarized IPL research on unwanted hair, vascular lesions, pigmented lesions, acne, and sun-damaged skin. Its conclusion was that most comparative trials found IPL to have effectiveness similar to lasers, rated at a level of evidence of "2b to 4, depending on the indication." Those are modest ratings, and the authors said so directly: "large controlled and blinded comparative trials with an extended follow-up period are necessary."
That review is from 2010, and devices have changed since. It's still a useful reminder that "works about as well as a laser in smaller studies" is the realistic expectation, not "proven superior."
What IPL is not a shortcut for
Not every brown patch is a sun spot. Melasma is a chronic pigment condition with its own causes and treatment approach, and it isn't one of the indications on the K261204 clearance above. If you have melasma, or aren't sure whether your patches are melasma, read our guide on how to treat melasma and get a diagnosis before you book any light- or heat-based treatment.

Why darker skin carries more risk
Dermatologists describe skin tone using the Fitzpatrick scale, from type I (very fair, always burns) to type VI (deeply pigmented). Because IPL targets pigment, people with more pigment in their skin have more tissue competing for the light's energy.
Cheryl M. Burgess, MD, a Washington, D.C., dermatologist, addressed this at the virtual Skin of Color Update meeting in 2020. Two trade publications reported her remarks:
•Dermatology Times reported that, according to Dr. Burgess, first- and second-degree burns are among the most common complications in patients with skin of color who undergo laser procedures, and that "they are particularly a problem with the use of intense pulsed light devices." She said these burns are easily recognized by their rectangular shape.
•MDedge reported that Dr. Burgess said IPL for hair removal "is not appropriate in patients with Fitzpatrick skin type IV or higher." She presented the case of a patient who developed first- and second-degree burns complicated by extensive loss of pigment after IPL.
Dr. Burgess also pointed to a gap in the data behind device settings. "Manufacturer-recommended parameters are based on clinical trials that enrolled mostly patients with Fitzpatrick skin types I-III and some patients with skin type IV, but rarely anyone with darker skin," she told Dermatology Times. For hair removal in skin of color, she described the long-wavelength 1064-nm Nd:YAG laser as a better fit because it "bypasses the melanin in the epidermis." Whenever she treats a new patient with skin of color using a laser, she recommends a test spot and a lower fluence (energy level).
A 2025 case report in Cureus (Kim and colleagues, PubMed 40955262) shows what can go wrong. Dermatologists in Mexico described a man in his late 20s with Fitzpatrick skin type IV who developed second-degree burns after IPL treatment for post-acne redness performed by a non-medical operator. He developed redness, blisters, and peeling, and needed oral medications, a corticosteroid ointment, and dressings, followed by further treatment. He improved significantly after four months, with minimal remaining hyperpigmentation. The authors concluded that the case "highlights the risks associated with IPL treatment administered by untrained personnel" and the need for "patient-specific parameter adjustments."
One case report doesn't tell you how often this happens. It does show the pattern the dermatologists above describe: a pigment-seeking device, skin type IV, an operator without medical training, and a burn.
What this means if you have medium-brown to deep skin
None of this means every IPL treatment on darker skin will go badly. It means the margin for error is smaller. Before you agree to IPL, ask:
•What Fitzpatrick type do you think I am, and how did you decide?
•For hair removal, would a long-wavelength laser such as Nd:YAG be a better option for my skin than IPL?
•Will you do a test spot first and wait to see how my skin responds?
•How will you adjust settings for my skin, and who decides them?
•How many patients with my skin type have you treated with this specific device?
•If I get a burn or a dark or light patch, who handles it, and is a physician available?
If the answers are vague, or you're told IPL is "safe for all skin types" without any discussion of settings or a test spot, take that as a reason to slow down.
Who may operate an IPL device
There is no single national rule on who may hold the handpiece. FDA clears the device and can limit it to prescription use, but states decide who may perform the procedure. Those rules differ widely, and they can differ within one state depending on whether the treatment is hair removal or something else.
Texas shows how layered this can be:
•Hair removal. Texas defines "laser hair removal" to include the use of "a laser or pulsed light device for nonablative hair removal procedures," so IPL hair removal is covered. Under Texas Health and Safety Code § 401.504, a person "may not perform or attempt to perform laser hair removal" without the appropriate state certificate, and facilities need their own license (§ 401.510). The Texas Department of Licensing and Regulation issues these.
•Treating conditions. Under § 401.521, a person may not operate a laser or pulsed light device "with the intent to treat an illness, disease, injury, or physical defect or deformity" unless the person is a physician, is acting under a physician's order, or is authorized by other law. A violation is treated as practicing medicine without a license.
•Device safety rules. The Texas Department of State Health Services rule at 25 Texas Administrative Code § 289.301 (effective December 17, 2024) does not require IPL devices to be registered, unlike higher-powered lasers. It does say lasers and IPL devices "must not be used on humans" unless under the supervision of a licensed practitioner of the healing arts acting within the scope of their license.
That's one state. Others handle IPL through medical boards, cosmetology boards, delegation rules, or not at all. If you're outside Texas, check your own state's rules, and in any state ask who will perform the treatment, what license they hold, and which physician or other licensed practitioner supervises them. Our guide on how to verify med spa provider credentials explains how to look up a license with your state.
Before you book
A short checklist:
•Get a diagnosis first. Know whether you're treating sun spots, redness, hair, acne, or something else, such as melasma, that needs a different approach.
•Ask which device. Get the brand and model and check its clearance in the FDA database.
•Ask about your skin type directly. Expect a real answer about settings, test spots, and alternatives.
•Ask who operates it and who supervises. Then check those licenses yourself.
•Watch for pressure. A large prepaid package sold before a test spot is a warning sign. Our unsafe med spa red flags guide lists others.
IPL can be a reasonable option for the right problem on the right skin. It's still a device that works by heating tissue, and it deserves the same scrutiny you'd give a laser.
