Background for Erasable ink for tattoo removal

Tattooing is a popular and widespread method of adding color to the skin by injecting colored pigment ink into the skin through small holes created therein with a needle or tattoo device. Millions of people have at least one permanent tattoo. With the popularity of “body art”, more young people are getting tattoos. The tattoos may be difficult to conceal depending on the location. Tattoos that were tattooed in youth can make it difficult to find employment and social acceptance later in life. There is a large market for tattoo removal.

Tattoo removal can be more painful, difficult and expensive than the original application. This involves injecting different colors into the dermis. The dermis, the outer skin layer that lies below the epidermis (a thin layer of skin about 1 mm thick), is the skin layer. Newly applied tattoos can cause ink pigments to clump near the epidermis. Early techniques for tattoo removal used abrasives, which were used to remove the epidermis and the tattoo pigment. This technique can cause permanent scarring and infection, and is therefore painful. Additionally, tattoo pigments can become encapsulated in the fibroblasts over time and migrate deeper into your dermis. This makes it more difficult to remove older tattoos by abrasion.

The laser was the first non-abrasive method for tattoo removal. In the 1960’s, experiments were made with laser energy applied to permanent ink tattoos. These experiments were done using continuous wave argon lasers and later carbon dioxide lasers. This effectively burned off the tattoo. Permanent scarring at the original location of the tattoo was an undesirable, but not unforeseeable side effect.

In the 1980’s, pulsed or Q?switched lasers were developed. This made it possible to treat a variety of dermatological pigmentation issues including tattoo removal. Q-switching allows for high-energy nanosecond pulses (or laser energy) from solid-state lasers. By selecting the wavelength of the laser or choosing a color that absorbs the laser energy faster than the surrounding skin, the tattoo can be removed using thermal photo ablation. The laser pulses can cause thousands of pigment particles in tattoo skin to heat up, photo ablate or break down into smaller pieces due to the thermal shock waves produced by the laser energy. Normal body processes can then diffusely remove the pigment fragments.

Tattoo pigments come in a variety of colors so there is no one laser wavelength that can be used to remove tattoos by photo ablation. Four factors are required to selectively ablate ink pigments.

The main sources of trauma in laser treatment and tattoo removal are the application of laser energy and the resulting heating and formation of thermal shock waves in dermis. It is common to require multiple treatments to remove a tattoo. These procedures can be painful and expensive, and may cause permanent scarring or pigment color variations.

Many attempts have been made in order to find a cheaper and more painless way to remove or conceal permanent ink tattoos. U.S. Patent No. No. No. To conceal the tattoo, the colored ink can be brushed on top of the original. The tattoo can be made permanent by injecting skin-colored ink. This method doesn’t affect the permanent removal of the tattoo, but it must be used on a regular schedule to keep the concealment.

Malak discloses methods and devices for Plasmon Enhanced Cosmetic and Medical Procedures in U.S. Patent Application No. US 2005/0203495, published Sep. 15, 2005. This publication suggests that magnetic nano bodies may be used to inject tattoo pigment particles into the dermis using nanosecond pulses laser energy. Laser energy pulses interact to the nano particles to produce surface plasmon resonance illumination (SPR), which photodecomposes the pigment. Malak’s method is still theoretical and requires a number of painful injections to make tattoos effective.

More recently, Smits et al. in U.S. Patent Application Publication No. 2012/0215209, Tattoo Removal and Other Dermatological Treats Using Multi-Photon Process, published August 23, 2012. This patent application discloses a method and system for removing a small portion of a tattoo by using a low-energy, multi-photon intense pulse light to treat the tattoo ink. Sits et al. The process claims to reduce tissue damage around the tattoo, but it doesn’t eliminate it. It still requires several passes to remove it effectively.

Considering the above, a tattoo removal method and system is required that provides effective, painless, and scar-free tattoo removal. This can be done economically in one session, without the need to have multiple treatments.


Accordingly, this invention provides an improved erasable ink and a method to remove tattoos using an Energy Transfer Photodisruptive Mechanism. This maximizes the efficiency of the transfer energy from a low-energy light source to a higher energy donor and then to the tattoo pigment molecule for photodecomposition.

In accordance to an embodiment, energy transfer efficiency is optimized by providing nanocrystal donors that are surface-treated for upconversion in near infrared (NIR), blue (UV) and ultraviolet (UV). These donors can be stably miscible in tattoo ink.

Another embodiment of the invention comprises sodium yttriumfluoride (NaYF4) nanocrystals that are doped with Rare Earth elements.

In another embodiment, the initiator/acceptors of upconverting are sensitive to UV radiation and blue light.

Another embodiment of the invention optimizes FRET efficiency by controlling the distance between donor and initiator/acceptor, controlling the spectrum overlap between donor emission spectrums and acceptor absorption spectrums, and controlling relative orientation of donor emission dipole moment versus acceptor absorption dipole moment.

In another embodiment, the photodecomposition process can be initiated by exposing the area tattooed to ultraviolet energy.

These and other objects of this invention will be obvious from the accompanying description and supporting materials.
