Intense pulsed light (IPL), diode laser and Nd:YAG laser each remove hair by heating the follicle, but they differ in precision, comfort and the skin types they suit.
IPL
IPL emits a broad spectrum of light rather than a single wavelength. It is versatile and cost-effective and can also address pigment and vascular concerns, but it is generally less selective than a laser, so results depend heavily on operator skill and correct filtering.
Diode Laser (808 nm)
A single, deeply penetrating wavelength makes the diode laser fast, comfortable and effective across a wide range of skin types — the reason it has become the clinic standard for hair removal.
Nd:YAG (1064 nm)
The longer 1064 nm wavelength penetrates deepest and is absorbed less by epidermal melanin, which makes it the safest option for darker skin tones. It is also central to tattoo and pigment removal.
Which Should You Offer?
Many clinics run a diode laser as their primary hair-removal device and add Nd:YAG for darker skin and pigment work. Match the technology to your client demographics and the treatments you plan to market.
