Alexandrite Q-Switched Laser

Q-Switched Alexandrite laser treatments in NYC are ideal for treating pigmented lesions such as freckles, birthmarks, and moles, as well as tattoo removal. The laser produces a short, high power pulsed beam, which allows for the production of light pulses to be much higher than a continuous, constant beam. Q-Switched lasers are considered the gold standard for most laser tattoo removal procedures because the repetition and high pulsed energies have the ability to more effectively break up the ink into particles small enough for the patient’s own immune system to flush out.

The Alex laser is effective for all colors except for yellow and red, while ND:YAG laser is effective for most colors except for green and yellow. The Q-switched laser uses a high-intensity pulse beam that is directed deep within the skin to break down the ink. Once the ink is broken down into small enough particles, the body absorbs it, while also stimulating collagen production. Studies have shown that tattoos can be significantly reduced in appearance over a series of Q-Switched Alexandrite laser treatments1. The success rate typically increases with the number of treatment sessions.

Because Q-switched lasers2 have the capability of selective photothermolysis, precise targeting of a structure or tissue using a specific wavelength of light that selectively absorbs light into that particular target area alone, they are also considered an effective treatment for laser hair removal, the reduction or removal of hyperpigmentation, broken blood vessels and hemangiomas.

Fractional laser resurfacing and Q-Switched lasers are often in combination. Combining fractional resurfacing with Q-Switched laser therapy, such as the Ruby laser, to remove unwanted tattoos has shown significant promise in achieving the desired effect.
