Dear EarthTalk: My daughter loves those press-on tattoos, and they’re frequently given out at birthday parties and other events. But I’ve noticed the labels say they’re only for ages three and up. Are they safe? If not, are there alternatives? -- Debra Jones, Lansing, MI
For the most part, so-called temporary tattoos are safe for kids and grown-ups alike, even if they do contain a long list of scary sounding ingredients including resins, polymers, varnishes and dyes. But if they are sold legitimately in the U.S., their ingredients have been approved by the U.S. Food and Drug Administration (FSA) as cosmetics, meaning the agency has found them to be safe for “direct dermal contact.” The FDA has received reports of minor skin irritation including redness and swelling, but such cases have been deemed “child specific” and were not widespread enough to warrant general warnings to the public.
