The following is a summary of “Process of Sterilizing Tattoo Inks Releases Formaldehyde,” published in the December 2023 issue of Dermatology by Lee, et al.

Tattoos are a common form of body art, with approximately 12% of Europeans and 20% of Americans having at least one tattoo. However, the chemicals in tattoo inks used to create these designs raise concerns about potential health risks. Formaldehyde, a known harmful substance, is a chemical found in tattoo inks. Despite its prevalence, the factors contributing to formaldehyde levels in tattoo inks and their potential health implications remain poorly understood.

For a study, researchers sought to assess the levels of formaldehyde in tattoo ink products sold internationally and identify the factors influencing its production. Additionally, they explored potential methods to mitigate formaldehyde generation in tattoo inks. The investigation involved testing seven tattoo inks sourced from different brands.

The study’s findings revealed that formaldehyde release was primarily linked to the gamma radiation sterilization process used on tattoo ink products. This is a crucial piece of information for tattoo artists, as they need to be aware of the potential risks associated with the sterilization process. Moreover, the study observed higher levels of formaldehyde in tattoo ink compositions containing organic components compared to those with inorganic components, regardless of sterilization method or container type. Notably, glycerin released over seven times more formaldehyde than other components during gamma-ray sterilization, a finding that should prompt caution among tattoo artists.

The study underscored the need for further research to understand the chemical reactions occurring during sterilization procedures and to explore alternative sterilization methods that minimize formaldehyde formation. It also highlighted the importance of developing tattoo inks with reduced formaldehyde content and implementing stringent quality control measures. These measures are crucial to ensure the safety of tattooing practices, a matter of utmost concern for regulatory authorities and researchers in dermatology and public health.
