What is a common health risk associated with using non-FDA approved ink?

The increased likelihood of allergic reactions is indeed a critical health risk linked to the use of non-FDA approved ink. Non-FDA approved inks may contain harmful or untested ingredients, which can provoke immune responses in some individuals. These reactions can manifest as itching, swelling, redness, or more severe allergic complications, especially for those who may have sensitivities to certain pigments or additives not regulated by health authorities.

Choosing inks that have been evaluated and approved ensures that they meet safety standards and are less likely to contain harmful substances. In contrast, options like higher cost, better quality, or longer healing time do not directly address the specific health concerns associated with the ingredients in non-regulated inks. Thus, the primary focus regarding health risks is on the potential for adverse effects like allergic reactions, making this the correct focus in understanding the implications of using unregulated products.
