Even though a tattoo constitutes a fashion phenomenon, most ignore the negative after effects of tattoos.
It's constantly advertised for aesthetic reasons, assumingly, but the essence is one. The person itself, and by itself is committing an act of barbarism against his body, because via the inks used, it's inserting heavy metals to it.
We know how negative their effect is within the human body and we have seen the evolution of dentistry, which has slowly but surely removed heavy metals from its weaponry entirely, because of their toxicity.
However, the tattoo fashion continues on, even though we become more and more aware with accuracy, re: the components of the inks, since it was proven that they have an intake of mercury, lead, antimony, beryllium, cadmium, arsenic.
As if all these elements were not enough, within inks we find dangerous phthalates or even hydrocarbons.
The question therefore is, why isn't there a more intense notification and information at a scientific level, especially towards the younger ones, who are more easily affected by fashions, because they don't necessarily comprehend that it's regarding an irreversible action, and that consequently even its correction is dangerous for the body and not so effective at that.
Let them at least be aware of it prior, and not learn about it when it's too late.
