Certain colors have proved more difficult to remove than others. In particular, this occurs when treated with the wrong wavelength of laser light is used. Some have postulated that the reason for slow resolution of green ink in particular is due to its significantly smaller molecular size relative to the other colours. Consequently, green ink tattoos may require treatment with 755 nm light but may also respond to 694 nm, 650 nm and 1064 nm. Multiple wavelengths of light may be needed to remove colored inks.
Dye modules are available for some lasers to convert 532 nm to 650 nm or 585 nm light which allows one laser system to safely and effectively treat multi-color tattoo inks. When dye modules take 532 nm laser wavelength and change it, there is a loss of energy. Treatments with dye packs, while effective for the first few treatments, many not be able to clear these ink colors fully. The role of dye lasers in tattoo removal is discussed in detail in the literature.
With four distinct Q-switched mode wavelengths – 1064 nm, 532 nm, 585 nm, 650 nm, the robust Spectra has the versatility to provide our patients with a wide range of clinical options. And, Spectra is the first Q-switched Nd:YAG laser cleared for the treatment of melasma. The technically advanced Spectra system offers an edge over other lasers and provides enhanced clinical outcomes.
Another common smaller tattoo for people to get is a simple letter. The letter P may symbolise the persons first name, someone’s name that’s important to them or even the periodic symbol for Phosphorus. There are thousands of fonts to choose from and luckily with letters it’s easy to test them out on your computer before you pick which one will look best.
