The "ruby" is a gem-toned take on the Q-switched laser. It delivers reddish colored laser energy in pulses, which is absorbed by the skin's melanin (cells responsible for dark color), making it a good option for tattoo removal.
The Q-switched ruby laser (QSRL) operates at a wavelength of 694 nm and was the original, but now defunct, method for laser hair removal. (The ruby has since been replaced by the more efficient alexandrite and diode lasers, which use longer wavelengths to better reach into the skin and zap the roots of hair follicles.)
The QSRL penetrates just one millimeter under the skin, heating and destroying tattoo ink so it can be naturally flushed from the body.
What It's Good For
The QSRL can remove black and blue ink.
Who it works for: The ideal candidate for treatment with the ruby laser is one who is fair skinned and burns easily in the sun. If your porcelain complexion resembles that of Nicole Kidman's, you're a good candidate.
Recommended age range: There is no recommended age range.
When will I see results?: Four to five treatments are normally required to remove black and blue tattoo ink with the ruby laser.
How long it lasts: As expected, everyone reacts differently to laser tattoo removal. Tattoo removal is permanent, but the ruby laser may not always remove every last drop of ink from under the skin.
It's possible for a "shadow" of your former tattoo to remain after several ruby laser treatments.
Key benefits of Ruby Laser: Ruby laser are an effective form of tattoo elimination in patients with light skin.
Licensed uses: Ruby laser are approved for tattoo removal.
