Alexandrite vs Nd:YAG Laser Hair Removal: What’s the Difference?

Laser hair removal systems may use different wavelengths to target pigment associated with the hair follicle. No single wavelength is automatically best for every person. Skin tone, hair colour, hair thickness, treatment area, recent sun exposure and treatment settings all influence which approach may be appropriate.

What is Alexandrite laser?

Alexandrite laser technology commonly operates around 755 nm. It is frequently used for hair reduction in lighter skin tones with pigmented hair because this wavelength is strongly absorbed by melanin. As skin pigmentation increases, settings need to be selected carefully.

What is Nd:YAG laser?

Nd:YAG laser technology commonly operates around 1064 nm. Its longer wavelength is less strongly absorbed by epidermal melanin, which is why it is often considered for darker or more pigmented skin tones. Hair and skin characteristics still need to be assessed before treatment.

How do Alexandrite and Nd:YAG differ?

The two wavelengths interact differently with pigment in the skin and hair. Alexandrite is often selected for lighter skin tones, while Nd:YAG may be considered when more epidermal pigment is present. The appropriate choice depends on the individual rather than on one device name alone.

Why treatment settings matter

Laser wavelength is only one part of treatment planning. Pulse duration, energy, spot size, cooling, treatment area and the patient’s skin and hair characteristics all affect the procedure. A consultation helps the provider select settings appropriate to the individual.

Cooling and comfort

Modern laser systems may use integrated cooling to support skin protection and improve comfort during treatment. Sensation still varies by treatment area and individual sensitivity.
