Nd:YAG lasers derive their name from the yttrium-aluminum-garnet crystal that emits light energy during the treatment. These lasers treat skin problems such as scars, prominent veins, and fine lines. They are also commonly used for hair removal.
Most hair removal systems work by targeting and destroying the pigment melanin in the hair follicles. Nd:YAG lasers are different. They do not focus on the melanin in the epidermis of the skin, so they are safe to use on darker skin tones and various hair types. However, it is less effective on lighter-colored hair than other laser types.
Overall, the Nd:YAG laser is one of the most effective hair removal treatments. Its long wavelength can target large areas faster, reducing the duration of the treatment session. It works by penetrating 5-7mm into the skin and destroying the hair follicles to reduce hair growth. As it targets the lower layers of skin, it keeps the surface intact without causing any damage to the surrounding skin. While this laser is ideal for treating larger areas, it may not be suitable for removing fine hairs.
Nd:YAG hair removal requires a few more treatments than other laser hair removal systems. Treatments with this type of laser may feel uncomfortable, and patients may experience some redness and swelling after, but this will subside. Providers recommend their patients schedule a total of 4-5 sessions that are spread 4-6 weeks apart for optimal results. The final results are smoother, hairless skin, which can last more than 12 months.
