In a paraphrase, Val takes information from a sentence or a group of sentences and puts it in her own words. This means that Val's paraphrase should not use the same structure as the original sentence nor the same words (except for words that are essential to the concept. In this case it would be difficult to rewrite the sentence without using either "tattoo" or "ink.")
"While state and local authorities oversee the practice of tattooing, ink and ink colorings (pigments) used in tattoos are subject to FDA regulation as cosmetics and color additives."
The US Food and Drug Administration makes rules about tattoo ink, and cities and states are in charge of tattoo parlors (US Food and Drug Admin.)
