A buying guide for IPL machines: how IPL works, wavelength filters, energy, spot size and what to check for a versatile salon workstation.
Intense Pulsed Light (IPL) is a versatile, non-laser light therapy used for hair removal, skin rejuvenation, pigmented and vascular lesions, and acne. Because it uses broad-spectrum light filtered to different wavelength bands, one IPL platform can cover a wide treatment menu — which is why it is popular with salons that want breadth from a single machine.
The interchangeable filters determine which treatments the machine can perform. More filters mean a wider menu — hair removal, photorejuvenation, vascular and acne all use different bands. Check the filter set included and whether additional filters can be added later.
Energy density (measured in J/cm²) and spot size determine treatment speed and depth. A larger spot with adequate energy treats faster, while adjustable energy lets you match the setting to skin type and indication. Look for a machine with a useful energy range rather than a single fixed output.
Optimal Pulse Technology (OPT) is an advancement on traditional IPL that delivers more consistent square-wave pulses. This improves comfort and results, and is worth understanding when you compare machines — OPT platforms are often marketed as the premium IPL option.
IPL is often the most affordable entry into light-based treatments and a strong first machine for a new salon. It lets you test demand across hair removal and skin treatments before investing in more specialised, higher-cost systems like diode or HIFU.
IPL gives long-term hair reduction and works well on suitable hair and skin types, though diode is generally faster and more effective on coarse or dark hair. IPL's strength is versatility across many treatments.
OPT is an improved form of IPL that delivers more consistent square-wave pulses for better comfort and results. It is essentially a premium version of the same technology.
With the right filters, a single IPL platform can cover hair removal, photorejuvenation, pigmented lesions, vascular lesions and acne — making it a multi-purpose workstation.
