I have tiny thin hairs on my back that I don't like because when I go to a pool and they get wet its very noticeable as they darken when wet. So I started using hair removal cream there. But now I have a tattoo now for a month and a bit and I was wondering if it is safe to use the Nair hair removal cream for sensitive skin without wrecking or causing any damage to my tattoo?

Once the tat is completely healed, the Nair should not affect it. But the longer you wait, the less likely it is that anything will happen to it.
