Tattoos are balls of ink that are injected into the superficial layer of the skin. These balls of ink are then stored amongst immune cells in the second layer of the skin (the dermis) where they get stuck and are too large to be carried away.
Extremely short nanosecond bursts of light energy penetrate the skin through the tattoo ink pigment leaving surrounding skin untouched. The laser passes beneath the first layer of the skin into the dermis (the second layer) where the ink molecules absorb the laser energy and are shattered into smaller pieces that are then absorbed into the blood stream. The body will then begin the process of harmlessly removing the ink through the lymphatic system which will take a minimum of 6 weeks for the process to be successful.
Each treatment will continue to target the tattoo ink pigment, each time shattering into smaller microscopic pieces eventually dissipating and allowing no visible particles. Just like the sun is attracted to a black t-shirt yet reflects a white one, the surrounding skin with no tattoo pigment will simply reflect the laser and remain unaffected.
During treatment the tattoo will appear to have a white surface layer which is the first initial sign that the process is working. This is caused by the breaking down of tattoo pigment and the reaction to the laser, this colouring will subside within a couple of hours.
Immediately after treatment the surrounding skin is likely to show a red discoloration and mild swelling. The feeling can be compared to mild sunburn where swelling and redness may last for one week. We will continue to cool the area at minus 40℃ using our optimised skin cooling machine.
