Classically, it was thought that tattoos dyed the cells in the dermis of the skin and that the pigment-bearing cell lived forever, allowing the tattoo to be permanent.
The cells die and transmit the pigments
However, French researchers have discovered that the skin cells which carry the tattoo pigment are not eternal and that these cells transmit the pigment to new cells when they die, dynamically ensuring long-term persistence. tattoos.
Destroying these cells would increase the effectiveness of the laser
According to the researchers, acting on this process would make it possible to further improve current erasure techniques, carried out by laser pulses. The laser causes skin cells to die and their pigments to fragment. These can then be transported away from the skin via the lymphatic vessels which drain the skin.
To improve this action it would be necessary to proceed to the temporary elimination, around the tattooed area, of the cells which transmit the pigment, so that the fragmented particles of pigment generated by the laser pulses are not immediately re-captured by other cells. .
A prospect that will delight the many tattoo aficionados, for those of them who ultimately no longer feel in tune with the patterns they have chosen to have traced on their skin.
