January 19, 2016 / Laser Tattoo Removal


A tattoo is a grouping of ink and dye particles imbedded beneath the top layer of the skin. They can be decorative, cosmetic (eg. permanent lip- or eye liner) or caused by injuries where pigment (from substances such as dirt and pencil marks) becomes embedded beneath the skin.

Because the body is not able to absorb such concentrated deposits of pigment, it forms a protective layer of collagen around the tattoo, making it permanent. At least, it used to be.

Modern laser technology has enabled to undo (or at least reduce) mistakes or regrets, sending pulses of high energy light into the skin, fragmenting the tattoo ink into thousands of tiny particles.

These tiny particles are small enough to be gradually absorbed and dispersed by the body. There is usually some pain or discomfort during treatment, although a local anaesthetic helps.

Since different lasers are needed to erase specific colors in a tattoo, multi-colored tattoos require several treatments to completely erase.

The most common (non-ablative) laser types used for tattoo removal include:

Q-Switched Ruby Laser

This was the first laser used for tattoo removal. The light wavelength of 694nm makes this useful for green tattoos (the most difficult to remove). Although special care must be taken when treating someone with dark skin, this laser is still very useful for removal.

Q-Switched Nd:YAG Laser

Can operate alone at a wavelength of 1064nm (effective for removal of dark blue or black ink) or with a frequency-doubling crystal to shorten the wavelength to 532nm (effective for removal of red or orange ink).

Q-switched Alexandrite Laser

Is excellent for the removal of green and blue-black tattoos.

The number of treatments will depend on the type and depth of ink; on average 3-6 treatments, but even as many as 12, about a month apart.
