1064nm Nd:YAG Clinical Profile
The 1064nm Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) wavelength penetrates deeper than any other standard aesthetic laser. Its relatively low absorption by epidermal melanin makes it the only safe choice for hair removal on dark skin tones.
The Physics of 1064nm Nd:YAG
Because 1064nm light is poorly absorbed by melanin, it passes through the epidermis with minimal thermal damage. It scatters heavily in the dermis, where it is absorbed by hemoglobin in blood vessels or the dense melanin concentrations in deep hair bulb matrices. This requires higher fluences to achieve clinical endpoints compared to Alexandrite.
Primary Clinical Indications
- Hair Removal (Dark Skin)
- Deep Vascular Lesions
- Leg Veins
- Skin Rejuvenation
Frequently Asked Questions
Why is Nd:YAG the only safe laser for dark skin?
Its low melanin absorption allows the energy to bypass the heavy epidermal melanin found in Fitzpatrick V and VI skin types, targeting the hair follicle deep in the dermis without burning the surface skin.
Can Nd:YAG treat spider veins?
Yes, 1064nm is highly effective for deep vascular lesions, including leg veins, because it penetrates deeply and is absorbed by hemoglobin, causing the vessel to coagulate.
