Different laser wavelengths interact with pigment and tissue differently.
Is Alexandrite better than Nd:YAG for laser hair removal?
Neither wavelength is universally better. The appropriate wavelength and settings depend on skin tone, hair characteristics and treatment area.
What matters most?
The goal is to heat the hair target while protecting surrounding skin.
- Skin phototype
- Hair pigment
- Hair thickness
- Treatment area
- Recent tanning
- Laser settings
Why the answer can be different for each patient
A wavelength suitable for light untanned skin may not be the best choice for a darker skin tone.
What should you ask during consultation?
- Which wavelength is planned?
- Why is it appropriate for my skin?
- How are settings adjusted?
- What cooling method is used?
Incorrect settings can increase the risk of burns and pigment changes.
