Our story

People change. Tattoos don’t have to be forever.

Millions of people want more than tattoo removal. They want experts they can trust, honest guidance, and a place where they feel welcome at every step.

That’s why we started Undo in Amsterdam in 2015. And it’s why we’re bringing it to Europe.

Our promise has always been the same: the best possible treatment. We keep it treatment by treatment, expert by expert, clinic by clinic and, now, market by market.

Since last year, Undo brings together the leading tattoo removal specialists across the Netherlands, Sweden, Norway, Finland, Estonia and, as of June 2026, the UK.

We grow to one end: to be the foremost experts in tattoo removal defining what a happy outcome means, clinically and personally.
