Energy Absorption, Photoacoustic Effect and Lymphatic Drainage
Tattoos are made by using a tattoo needle to deposit tattoo ink particles of various colors, or chromophores, in the dermis layer of the skin. Immune system cells then take up chunks of the ink particles where the Tattoo Needle deposits them, becoming immobile for the life of the patient and thus preserving the tattoo image on a person’s skin. In LASER tattoo removal, the tattoo ink particles absorb the very high LASER light energy, heat up extremely rapidly, and result in a microscopic explosion, call the Photoacoustic effect. After the chunks of ink particles explode, they become smaller making it easier for the bodies immune system to carry the ink particles away, thus fading/removing the Tattoo.
Graph of skin absorption vs. light energy wavelength
The Quanta Q + C in the FIRST LASER in Ohio that has 3 dedicated TRUE LASER wavelengths including 532nm, 694nm and 1064nm. The 1064nm wavelength has the lowest absorption effect on hemoglobin (blood) and melanin (natural skin color/tone) and is therefore the safest wavelength for most early tattoo removal treatments. HbO = Oxyhemoglobin (arterial blood), H2O=water, HbR = deoxyhemoglobin (venous blood).
