IPL vs laser hair removal is the question we get asked most often — partly because of the name on our door. The short version: IPL (intense pulsed light) is a broad, filtered flash of many wavelengths, while a hair-removal laser fires a single wavelength chosen for your skin and hair. Both heat pigment in the follicle, but the laser does it with far more precision, which is why our laser hair removal Montreal program runs on three true lasers — Alexandrite, Diode and Nd:YAG — and not on IPL. IPL is still part of what we do; we just use it where it belongs, on sun spots and redness. This guide explains what separates the two technologies, which one the evidence favours for hair, what to make of at-home IPL devices, and how to tell whether you are a good candidate at all.

What this article covers

Is IPL actually a laser?

No. IPL stands for intense pulsed light, and the “light” is the giveaway: an IPL device is a very bright flash lamp, not a laser. It releases a broad spectrum of wavelengths in every pulse — typically somewhere between 500 and 1,200 nanometres — and uses cut-off filters to remove the portions the operator does not want. A laser, by contrast, produces a single, coherent wavelength. That one difference explains almost everything else about how the two technologies behave on hair.

That versatility is IPL’s real strength — and the reason it has a long, legitimate history in dermatology for vascular and pigmented lesions. It is also why, as the StatPearls review of IPL notes, the technology was first developed in the 1990s for leg veins, not hair. Hair reduction came later, as one of several uses.

How do IPL and laser hair removal actually work — and where do they differ?

Both rely on the same principle, selective photothermolysis: light is absorbed by the melanin in the hair shaft, converts to heat, and damages the follicle enough to stop or slow regrowth. The sequence is identical. What differs is how much of the energy reaches the follicle, and how much is wasted or absorbed somewhere it shouldn’t be.

Which works better for hair removal — IPL or laser?

For hair, the laser. IPL can and does reduce hair on fair skin with dark hair — it is not a scam, and plenty of people have had acceptable results with it. But the American Academy of Dermatology’s rule of thumb for laser is roughly a 10–25% reduction after the first session, building toward 70–90% over a course of 4 to 8 treatments, and lasers reach that ceiling more reliably and in fewer visits. IPL’s broad band means each pulse is less efficient at the follicle, so courses tend to run longer and results tend to be less even, especially on finer or lighter hair.

One honest caveat: the machine is only half the result. A well-run IPL treatment by a trained operator will beat a badly configured laser every time. The technology sets the ceiling; the person holding the handpiece decides how close you get to it.

Is IPL safe for darker or tanned skin?

Generally, no — and this is the clearest line between the two technologies. Because IPL is a broad spectrum with a lot of energy in the shorter, more melanin-hungry wavelengths, the epidermis of a deeper skin tone absorbs a large share of every pulse. That is where burns, blistering and post-inflammatory hyperpigmentation start. Most IPL manufacturers and clinics restrict hair-removal use to Fitzpatrick I–III, and a summer tan temporarily moves you down that same ladder.

What about at-home IPL devices?

Home IPL handsets are the reason the “IPL vs laser” question has become so common. They are real IPL, but at a fraction of a clinic device’s energy — that is what allows them to be sold for unsupervised use. Judged for what they are, they are a maintenance tool: with steady weekly use over months, many people see slower, finer regrowth on fair skin with dark hair. Judged against a clinic laser course, they are a different category of product.

If you already own one and are happy with it, keep using it — on the zones and skin tone it is designed for. If you are deciding between a device and a clinic course, the fair comparison is not price on day one but hours per year and how much hair is actually gone at the end of the course.

Alexandrite, Diode or Nd:YAG — which of our three lasers is yours?

Because no single wavelength is right for every skin, we run three. The choice is made at your consultation from your skin tone, hair colour and thickness, and the zone being treated — and confirmed with a patch test before any full zone is done.

If you want the engineering detail behind each platform — pulse widths, cooling systems, what actually changed in 2026 — our overview of current laser hair removal machines and technologies goes deeper than we will here.

So why is a clinic called IPL Lab removing hair with lasers?

Because IPL is a genuinely excellent technology — for the right job. Intense pulsed light targets pigment and blood vessels near the surface, which is exactly what you want when the problem is sun spots, freckling, broken capillaries or diffuse redness. That is what we use IPL for: our IPL/BBL photofacial is a core part of our hyperpigmentation and melasma treatment menu, and we have written separately about whether IPL works on sun spots. For hair, the evidence, the safety margin on darker skin and the session count all favour a true laser, so that is what we run.

The honest way to settle IPL vs laser hair removal is to admit the two technologies are not rivals; they are colleagues with different jobs. A clinic that uses IPL for everything is asking one tool to do two things. A clinic that refuses to use IPL at all is leaving a very good photofacial on the table. We do both, each where it earns its place.

How many sessions does laser take, and who isn’t a candidate?

Any light-based treatment — IPL or laser — only disables follicles in their active growth phase, and at any moment only a fraction of your hair is in that phase. That is why a course is a series, spaced about 4 to 6 weeks apart so each session catches a new cohort. On a laser, 4 to 8 sessions per zone is the norm; dense, hormonally driven zones such as the chin, jawline or bikini may need the longer course, and an occasional maintenance session afterwards is normal. Our guide to how long laser results actually last covers what “permanent reduction” really means.

Which package fits the zone you want treated?

Every course below runs on the laser that suits your skin — Alexandrite, Diode or Nd:YAG — decided at your free consultation with a patch test. Current package pricing is confirmed at your consultation; each card links to its own package page.

The full range — including 4-session starter courses and electrolysis for light hair — is in our hair removal package category. Men’s zones and pricing are covered on our men’s page.
