Greetings. Well that is an interesting question and i am glad that i may be able to help you in clearing your doubt. Do you know that, Many AUTOIMMUNE DISEASES, Cancer, are now linked to toxins in Tattoo ink. -- What does Laser Tattoo Removal do? The laser works by targeting the unwanted tattoo and exposing it to a beam of intense laser light, delivered in pulses. Each pulse of light disintegrates the dye, breaking it up into manageable particles that can be eliminated naturally by the body’s filtration system. The tattoo will not disappear. Rather, it typically fades over a period of time following each session. Tattoos generally require 8-10 treatments performed at regular intervals. To ensure optimum success, an interval of 4-6 weeks is normal between treatment sessions. Although the exact number of sessions required depends on a number of factors, including the size, color, depth of ink and type of tattoo. A very chronic tattoo skin cell reaction induced to an old cosmetic tattoos after an intense pulsed light (IPL) treatment for facial skin rejuvenation is reported. On the whole i suggest that IPL treatment should be used cautiously in patients with tattoos, especially when a history of AUTO IMMUNE DISEASE (viz.,HASHIMOTO) is present. Discuss with your doctor the reasons why you want your tattoo removed & don t forget to ask your physician about the risks associated with the procedure. This is just a guidance and not a definitive treatment. Hope i guided you rightly & helped you to make decision.
