IPL vs laser hair removal: what's the difference?
Reading time: 6 min. · Updated: 11/2026
Laser and IPL are often mentioned in the same breath, and many providers use the terms interchangeably. Both work with light and both can reduce hair. Technically, however, they are different methods – and that affects who they suit. Here's how they compare.
The short answer
A laser emits light of a precisely defined wavelength; devices with several wavelengths combine several laser sources. IPL ("Intense Pulsed Light") is not a laser: a flash lamp emits light with a broad spectrum, which is narrowed down with filters. This means a laser can be adjusted more precisely to skin and hair type. Both methods need several sessions, and neither works on light, red, grey or white hair.
Laser and IPL compared
| Laser | IPL | |
|---|---|---|
| Light source | laser (diode, alexandrite, Nd:YAG) | flash lamp |
| Light | one defined wavelength, e.g. 755, 810 or 1064 nm | broad spectrum, approx. 500–1200 nm, filtered |
| Settings | precisely tailored to skin and hair type | less precise |
| Darker skin types | can be treated with longer wavelengths (1064 nm) | limited |
| Light, red, grey hair | not effective | not effective |
| Sessions | several, usually 6–10 | several |
| In the studio | only with certified expertise under the NiSV | only with certified expertise under the NiSV |
| At home | a few low-power devices | many devices available |
How laser and IPL work
The principle is the same for both: the light is absorbed by the melanin in the hair, converted into heat and damages the structures of the hair root that are responsible for growth. Experts call this selective photothermolysis.
The difference lies in *which* light arrives. With a laser, it is one wavelength that matches the target. With IPL, it is a range of wavelengths – part of it is absorbed well by the hair, part of it more by the skin. That doesn't make IPL ineffective, but it does make it less precise.
Which skin and hair types?
Both methods work best on dark hair on light skin. The darker the skin, the more light the upper layer of the skin absorbs as well – and the greater the risk of burns and pigment changes. A laser with a long wavelength (1064 nm) is absorbed less by the melanin in the skin and therefore allows darker skin to be treated more cautiously. With IPL, this is more difficult.
On light blonde, red, grey and white hair, neither laser nor IPL works – the hair lacks melanin. Here, electrolysis (needle epilation) is the alternative.
Which works better?
Studies show hair reduction over several sessions for both methods. Direct comparisons vary and depend heavily on the device, the settings and the skin type. So the honest answer is: it depends less on "laser or IPL" than on whether the device suits your skin and hair, and whether it is set by someone with the right expertise.
The main argument for a laser is the more precise settings – especially for medium and darker skin types and for areas with strong, deep-seated hair.
Does laser or IPL hurt more?
You can feel both, usually as a warm tingling or a brief prick. How strongly depends mainly on the area, the settings and the cooling – less on whether it is laser or IPL. Many people describe modern diode lasers with a gliding technique and cooling in the handpiece as comfortable.
IPL or laser hair removal at home?
The devices sold for home use are mainly IPL devices, with a few laser diode devices too. They work at considerably lower power than studio devices so that non-professionals can use them safely. That usually means more applications, regular touch-ups, and a result that depends heavily on how consistently you stick with it. The NiSV expertise requirement doesn't apply when you use a device on yourself – so follow the instructions for use closely, especially regarding skin type and tanning.
What about "SHR"?
SHR ("Super Hair Removal") refers to a gliding technique with many low-energy pulses – not a separate light source. The term is used for both diode lasers and IPL devices. Ask what's behind it. More in the article Which laser suits which skin and hair type?
At MOOD Beauty
We work with a diode laser, the Alma Soprano ICE Platinum, with three wavelengths (755, 810, 1064 nm), cooling in the handpiece and a gliding technique. We do not offer IPL. The goal is a permanent¹ reduction – considerably less, finer and lighter hair over a long period.
¹ Permanent hair reduction requires several treatments, depending on the body area and the individual hair and skin type. Success cannot be guaranteed, even when the treatment is carried out professionally. On light, red, grey or white hair, the treatment is ineffective or only partially effective.
FAQ
No. IPL works with a flash lamp and a broad light spectrum, a laser with precisely defined wavelengths.
Both methods are safe when used by someone with the right expertise and with suitable settings. Risks arise mainly from incorrect settings, tanned or darker skin without adjusted settings, and a lack of caution on the face.
Yes. All that matters is the time since your last treatment and that your skin isn't irritated or freshly tanned. Tell us at your initial consultation what you've done so far.
With laser, usually 6 to 10, 4 to 6 weeks apart, more for some areas. More on this: How many laser sessions do you need?
