Tattoeage
Wanneer de inkt de lederhuid bereikt, gebeurt er iets geks. Je lichaam schrikt van de onbekende stof en wil het eigenlijk meteen zoveel mogelijk afvoeren. De pigmentdeeltjes zijn te groot om door ‘lichaamseigen opruimcellen’ afgevoerd te worden.

Om je toch te ‘beschermen’ kapselt de lederhuid de inkt in.

Door deze beschermingsreactie ontstaan er letterlijk bolletjes
inkt, die verder geen schade kunnen aanrichten en waardoor
de kleuren mooi en permanent in je huid blijven zitten.
