Removing Tattoos When They Are No Longer Wanted
Getting a tattoo often seems like a good idea at the time—especially
when you are young. In later years the tattoo may not seem to have been
such a good idea. A tattoo that "made a statement" in one’s youth can be
an embarrassment as one matures, becomes employed, gets married, etc.
Dermatologists can offer a number of methods of tattoo removal. The
choice of method depends on such factors as (1) the location of the tattoo
on the face or body, (2) the depth of tattoo pigment in the skin and the
extent to which it has migrated from the site of deposition, (3) the cost
of the procedure, and (4) the outcome desired by the patient.
Professionally applied tattoos are usually easier to remove than those
done by an amateur because the tattoo pigment tends to be more evenly
distributed under the skin. Tattoos by amateurs are frequently done by
depositing India ink under the skin with a needle, at varying depths under
the skin and at varying concentrations. Black and blue tattoos are the
easiest to remove; green and yellow are the hardest.
The older the tattoo, the more likely it is that pigment will have
migrated widely and deeply under the skin. Thus, some "old" tattoos may
not be completely removable by any means other than wide and deep surgical
excision. If surgery is agreed upon as the best treatment, patient and
physician should discuss the probable extent of the surgical scar and how
the scar can be minimized.
Other methods of tattoo removal include:
Salabrasion—Salt is used as an abrasive to peel away the tattoo
surface and underlying layers. Several salabrasion treatments may be
required. The salabrasion procedure can cause substantial discomfort for
some patients and it cannot remove pigment in deeper layers of skin. Local
anesthetic is administered to minimize discomfort. Healing requires
several days.
Dermabrasion—A rapidly rotating brush is used to remove
pigmented skin (Click on Treatments for Aging
Skin for a description of dermabrasion). Dermabrasion can often
remove all pigment in a professionally-applied tattoo, but if pigment has
migrated or been deposited in deep subcutaneous fat, complete removal by
dermabrasion may not be possible. Surgical excision is the only way to
remove all pigment when subcutaneous fat is involved. Local anesthetic is
usually administered to minimize discomfort. Healing may require several
days.
Chemical Peeling – Application of this acid to the skin can
remove tattoos in a cost-effective method but may leave a small scar.
Consult with your dermatologist to determine the best result in partial or
total treatment with peeling agents.
Laser removal—Removal of tattoo pigment can be done with
infrared lasers or color-specific lasers. Color-specific lasers such as
the Q-switched ruby laser and alexandrite laser, and the infrared Nd:YAG
and carbon dioxide lasers, have proven very effective in removing tattoos.
Multiple treatments are usually necessary, especially when tattoos are
multi-colored. Black tattoo pigment absorbs all laser wavelengths, making
it the easiest to treat. Other colors, such as green, selectively absorb
laser light. These colors can only be treated by selected lasers based
upon the pigment color. Similar to dermabrasion, results are influenced by
the depth of pigment in the skin and other factors. Local anesthesia is
usually given to minimize discomfort. The treated area is a burn that
heals over a number of days. Infrared lasers such as carbon dioxide
(CO2) and Nd:YAG are especially effective in removing large, superficial
tattoos with minimal subsequent scarring. The powerful infrared laser beam
can vaporize and remove pigmented tissue.
- Color-specific lasers remove tattoos by color-specific
absorption of laser energy by pigments in the tattoo. Destruction is
limited to pigments of the same color (wavelength) of the laser beam,
and at tissue depths were the laser beam can penetrate. It may be
necessary to use several color-specific laser beams over several
subsequent treatments to remove pigment from a multi-colored tattoo.
Q-switching technology that delivers short, powerful laser pulses has
improved the effectiveness of color-specific lasers in tattoo removal.
The most common complications of tattoo removal are scarring, and
residual pigment under the skin. It is helpful for a patient to know that
tattoo removal almost always results in a scar of some kind. The patient
and dermatologist should discuss the probability of scarring, and
post-procedure treatment for scarring. In some instances a choice must be
made between a more extensive procedure to remove all pigment, and a less
extensive procedure that may leave pigment in deep tissues.
