Tattoo removal - Side Effects
There are many reasons you may decide to remove a
tattoo. Perhaps it was done out of impulse and you regret getting
it. Or maybe you are dissatisfied with the way it turned out or are
experiencing an allergic reaction to the ink. Although expensive and
often painful, tattoo removal is possible. There are many procedures
that can help lighten or even completely remove the unwanted body
art. Long-term effects of laser tattoo removal are something to
consider if you are considering going through the treatment to get
rid of your ink.
Hyper- and Hypopigmentation
The process by which tattoos are removed via laser begins with a
laser emitting highly concentrated light beams into the skin. The
tattoo ink absorbs the light, which breaks the ink particles into
smaller, more manageable chunks that are effectively removed by your
body's immune system. In the process, occasionally the laser will
affect the epidermis by lightening or darkening the color of the
skin, according to Tattoo Health. This could leave you with
noticeably light or dark patches on your skin, where the tattoo was,
in the same general shape as the tattoo. This is a permanent
condition.
Scarring
When you have a tattoo removed via laser, you may endure bleeding
and blistering as a result of the intensive procedure. The blisters
can pop and secrete liquid, and remain open, leaving you susceptible
to infection, which in some cases can eventually lead to scarring.
Scars result when a wound doesn't heal well or heals too slowly, so
you may notice signs of scarring around the area where the tattoos
used to be. To ensure that scarring doesn't happen, obey the
warnings that your dermatologist gives you, including keeping the
area covered after the procedures, and keeping the area clean and
dry for faster, neater healing.
Partial Ink
Some colors of the spectrum don't absorb light very well, resulting
in partial tattoos or ink that cannot be removed. The easiest colors
to remove are black and gray, since both readily absorb the white
light from the laser. Unfortunately, lighter colors don't absorb as
well, which means some people with colored tattoos will still have
partial ink left, even after extensive laser treatment. The general
outline or some of the colors in the tattoo might be left behind and
deemed permanent by your dermatologist. Your options would be to
remove only parts of the tattoo, leaving the lighter portions
intact; cover the tattoo with a new tattoo; or leave the tattoo
as-is.
REMOVAL OPTIONS
Laser Treatment
According to the Skin Laser Center, laser treatments can be safely
used to remove tattoos. Laser systems, like the Palomar Q YAG 5,
work by focusing a laser on the tattoo. This laser passes through
the top layer of skin and into the ink of the tattoo. As your skin
absorbs the light, the resulting heat fractures the tattoo ink into
tiny fragments. The lymphatic system of the body then carries these
particles away to be shed naturally from the skin. The Mayo Clinic
explains that tattoos with several colors may require multiple
treatments with different laser wavelengths. After the procedure,
the skin may swell, bleed or blister. Use antibiotic ointment on the
affected area to encourage healing. Multiple sessions may be
required to lighten or erase the tattoo completely.
Dermabrasion
Experts at the American Society for Dermatologic Surgery explain
that dermabrasion is a common tattoo removal technique. In this
procedure, a doctor or dermatologist sands away the top layer of
skin, at the site of the tattoo, with a quickly revolving abrasive
brush or wheel. This technique helps the tattoo ink to leach out of
the skin. In addition, it encourages the body to absorb the leftover
ink. For several days after the procedure, the skin will feel sore
and irritated. A doctor may prescribe medication to help deal with
the discomfort. After about seven days, new skin will begin to form
to replace the tattooed skin.
Surgical Removal
Smaller tattoos can be surgically removed. The Mayo Clinic says that
a surgeon will first numb the skin with an anesthetic. Using a
scalpel, a doctor cuts out the tattoo and then stitches the skin
back tighter. An antibacterial medication will need to be used after
the procedure to encourage proper healing. Although this method is
effective, it will leave a scar behind-making it unpractical for
larger tattoos.
Worries About Pain
Homemade tattoos and any tattoo with deep blue and black ink colors
are among the most difficult to remove. The procedure is not
painless-people often describe the laser procedure as similar to
that of hot oil on the skin or a slap from a rubber band. Some
anecdotal reports indicate that patients who received anesthesia by
local injection required additional treatments, because the
injection causes swelling. This spreads the tattoo ink, and makes it
more difficult for lasers to act on ink particles.
Other Concerns
Side effects are usually minor, but can include skin discoloration,
infection or scarring. A raised or thickened scar may appear three
months to six months after tattoo removal. Some researchers are
trying to determine if tattoo removal treatments affect the lymph
nodes, with scientists in Europe reporting that lasers used on
certain pigments had created toxic or carcinogenic byproducts.
Number of laser treatment sessions needed?
Complete laser tattoo removal requires numerous treatment sessions,
typically spaced at least four to six weeks apart. Treating more
frequently than four to six weeks increases the risk of adverse
effects and does not necessarily increase the rate of ink
absorption. Anecdotal reports of treatments sessions at less than
four weeks lead to more scarring and dischromia and can be a source
of liability for clinicians.
At each session, some but not all of the tattoo pigment particles
are effectively fragmented, and the body removes the smallest
fragments over the course of several weeks. The result is that the
tattoo is lightened over time. Remaining large particles of tattoo
pigment are then targeted at subsequent treatment sessions, causing
further lightening. The number of sessions and spacing between
treatments depends on various parameters, including the area of the
body treated and skin color.
Tattoos located on the extremities, such as the ankle, generally
take longest. As tattoos fade clinicians may recommend that patients
wait many months between treatments to facilitate ink resolution and
minimize unwanted side effects.
Post-treatment considerations
Immediately after laser treatment, a slightly elevated, white
discoloration with or without the presence of punctuate bleeding is
often observed. This white color change is thought to be the result
of rapid, heat-formed steam or gas, causing dermal and epidermal
vacuolization.
Pinpoint bleeding represents vascular injury from photoacoustic
waves created by the laser's interaction with tattoo pigment.
Minimal edema and erythema of adjacent normal skin usually resolve
within 24 hours. Subsequently, a crust appears over the entire
tattoo, which sloughs off at approximately 14 days post-treatment.
As noted above, some tattoo pigment may be found within this crust.
Post-operative wound care consists of simple wound care and a
non-occlusive dressing. Since the application of laser light is
sterile there is no need for topical antibiotics. Moreover, topical
antibiotic ointments can cause allergic reactions and should be
avoided. Fading of the tattoo will be noted over the next eight
weeks and re-treatment energy levels can be tailored depending on
the clinical response observed.
