Nd:YAG can be used for which of the following treatments?

• A. Varicose veins, lentigines, tattoo removal
• B. Hair removal
• C. Skin resurfacing
• D. Acne treatment

Answer: (A)

Nd:YAG lasers operate at a 1064 nm wavelength, which penetrates deeper into the skin than many other laser wavelengths. That deeper reach makes them effective for targets beneath the surface, such as larger or deeper blood vessels (varicose or spider veins), pigmented lesions that reside deeper in the dermis (lentigines), and tattoo ink, especially dark inks, which absorb well at this wavelength. Because of this combination—vascular targets, deeper pigment, and tattoos—the Nd:YAG is well suited to these indications, which is why that option best fits what this laser is commonly used for. While it can be used for hair removal in some contexts, the trio of treatments listed aligns most directly with Nd:YAG’s strengths in vascular and pigment-targeted therapies.
