Overview of the Nd:YAG laser
The Nd:YAG laser, short for neodymium-doped yttrium aluminum garnet laser, is an essential aesthetic tool for numerous skin conditions. The specialized laser reaches deeper layers of skin, emitting a wavelength of 1064nm. That means it’s ideal for tackling pigmented skin concerns such as skin lesions, unwanted tattoos, and, in some patients, even laser hair removal. Nd:YAG lasers are also effective in skin tightening and overall rejuvenation. And because the Nd:YAG is nonablative, treatments do not impact the epidermis. Whether they need a YAG treatment to target melanin or tattoo ink, patients appreciate that the procedures are non-invasive and require minimal downtime, if at all.How does an Nd:YAG laser work?
As mentioned above, Nd:YAG lasers use a neodymium-doped yttrium aluminum garnet crystal to generate its laser. The neodymium ions are a catalyst for laser activity in the crystal. This allows the laser to reach deeper into the skin compared to other devices. Q-switched Nd:YAG devices like MediYag use two wavelengths: One for darker pigment or deeper penetration, and the other for lighter pigment or superficial skin concerns. That’s why practitioners laud Q-switched devices for their versatility: They can ensure effective pigment treatment for a diverse range of patients. The particles in question are easily targeted and naturally eliminated via the body’s lymph system.The benefits of Nd:YAG devices for laser tattoo removal
Q-switched ND:YAG devices vs other lasers
When considering laser technology for tattoo removal, there are several promising modalities and mechanisms on the market. You’ll find varying permutations of their features and capabilities, such as:- Picosecond lasers
- Q-switched neodynium: YAG lasers
- Q-switched alexandrite lasers
- Q-switched ruby lasers
- And, for certain limited indications, CO2 laser devices
