Understanding the Action of Light in Laser Hair Removal
The Motus AY laser machine uses two primary wavelengths:
755 nm (Alexandrite)
1064 nm (Nd)
These wavelengths interact with different chromophores:
Alexandrite (755 nm) is absorbed more effectively by melanin, making it ideal for targeting hair in lighter skin tones.
Nd (1064 nm) is absorbed by hemoglobin and penetrates deeper into the skin, making it ideal for darker skin tones and vascular treatments(Motus AY User Manual '22).
In laser hair removal, the primary chromophore targeted is melanin, which absorbs the light and heats the hair follicle, causing thermal damage to the cells responsible for hair growth.
Visual Aid: Include a diagram showing how light is absorbed by different chromophores at different wavelengths.
