Dermatologists We Quote

Some questions about tattoos are medical: whether it is safe with a skin condition or a medication, what normal healing looks like, what happens to ink in the body over time. On those questions TatSeek does not write its own opinion. We quote dermatologists who run tattoo clinics and publish on tattoo complications — word for word, with a link to the original paper — and then explain what that means in plain language.

Please note
  • These specialists are not affiliated with TatSeek, have not reviewed our pages and do not endorse TatSeek, any studio or any product.
  • Every quotation is copied exactly from their published, peer-reviewed work and linked to it, so you can read it in context. Our own explanation that follows a quotation never changes its meaning — if it does, please tell us and we will fix it.
  • Where a question is not covered by their work, guides cite public-health agencies (FDA, CDC, NIH), dermatology societies (AAD, BAD) and peer-reviewed studies instead, listed under “Sources” at the end of each guide.
  • Nothing on TatSeek is medical advice for your situation. If you have a condition or take medication, ask your own doctor before booking.

“From our point of view, there is no strict contraindication to getting a tattoo done; however, there is definitely a certain number of situations in which individuals who want to get a tattoo should first seek medical advice to determine whether or not they can get one and, if so, under which conditions they can get it.”

How we choose who to quote

  • Board-certified dermatologists for whom tattoos are a central part of their clinical and research work — people who run tattoo clinics or tattoo consultations, not general commentators.
  • Only peer-reviewed or institutionally published work that anyone can read, preferably open access.
  • We state the author’s role on multi-author papers (lead, senior or co-author) and flag industry-funded studies.
  • Quotations are short, exact and kept in context. When newer evidence changes the picture, we update the guide and its “last reviewed” date.
