new YORK (Reuters Health) – certain types of tattoos,

including those with yellow ink or blue and the oldest

and large, would be more difficult to eliminate that which is

made with laser traditional, according to a study in Italy.

but take up small with black ink tattoos

several years to disappear.

less than half of 352 people who wanted to delete a

tattoo with a laser by switching Q achieved his goal with 10

sessions and three-quarters did so after 15 sessions.

smokers and those who carried out the treatment with less

two-month interval were those who were less fortunate

to erase the tattoos.

chooses half of young people carried out a tattoo by

delete it. for that laser pulses are used to break the

ink. Then, immune cells eliminate those

particles.

the team of Dr. Luigi Naldi, of the Centro de Estudios

GISED of Bergamo, Italy, explained that the reaction of the laser with

pigments would make that blue and yellow inks will change of

color, but that do not disappear with treatment.

said that it is not a novelty and said that you people with

colorful tattoos “should know that deleting them is more difficult

and without the expected results”.

the effect of smoking is the ultimate result e

interesting and could be explained by its effect on the system

immune, said Naldi. “alters the function of the

cells responsible for deleting material (ink) excess”

after that breaks the laser.

PULSES MAS RAPIDOS, cleaning more fast

< p> En otro estudio tollenaar con el de Naldi nl archieven van

Dermatologie, VN-equipo de Estados Unidos probó un nuevo

dispositivo láser parabel eliminar tatuajes con un pulso más corto

(que dura un picosegundo) y lo comparó con el pulso tradicional

(que dura un nanosegundo).

“En los últimos 20 años geen hubo grandes cambios en los

tratamientos con láser para borrar los tatuajes”, dijo la

doctora Nazanin Saedi, autora belangrijkste del estudio de Thomas

Jefferson University, Filadelfia. Con el láser por conmutación

Q, “los pacientes fenêtre muchas sesiones para borrar un

tatuaje”. Cada sesión cuesta un par de cientos de dólares.

Para su estudio, 12 de 15 pacientes concurrieron een por lo

menos dos sesiones con la técnica de pulsos por picosegundo. een

los 12 se les había wegwerken por lo menos el 75 por ciento de

la ink and felt “satisfied” or “very satisfied” with the

outcome of two or four session.

research was carried out in the Center SkinCare Physicians

of Chestnut Hill, Massachusetts.

Saedi said that the company that manufactures the device,

Cynosure, partially financed the study and is making

clinical trials to seek its approval to the

Administration of food and medicines from United States.

a dermatologist alien to the study agreed that quantity

session necessary to erase a tattoo is a barrier

for many.

“the amount of people who are tattoo is growing (…),

which means that within 10 or 20 years it will also increase the

amount of people who want to remove their tattoos”, said the

doctor David Goldberg, director of laser research of the

Department of Dermatology of the school of Medicine of Mount

Sinai, New York.

clarified also that “the amount of people who manage to

erase a tattoo is very small (…) and that happens in part

because many sessions are needed to achieve this”.

Goldberg noted several limitations of lasers with

PS pulses, as its repeated troubles and his

high cost. but considered that in the coming years, new

lasers will “transform” the removal of the tattoos.

for now, the decision must be taken with seriousness. “done

a tattoo takes between a half and one hour, but delete it delay

years”, ended Goldberg.
