Temporary tattoos, including decal tattoos, henna, and "black henna," are popular for body art but come with potential risks. The FDA has received reports of adverse reactions to these products. Here's what you need to know:
Decal tattoos can last from a day to over a week. They come in two forms: one with a removable backing and another with an adhesive layer. While some adhesives protect the skin from harmful dyes, other ingredients might still cause allergic reactions. Always test on a small area before use, especially on sensitive facial skin.
Henna, derived from a plant, is only FDA-approved as a hair dye, not for skin application. Products marketed as "black henna" or "blue henna" often include harmful additives like p-phenylenediamine (PPD), a substance that can cause severe skin reactions. By law, PPD is not permitted in skin-applied cosmetics, yet these products are still found on the market.
Cosmetics sold to consumers must list their ingredients. However, products used in salons or temporary tattoo booths are exempt, leaving consumers unaware of potential allergens.
The FDA regulates color additives in cosmetics and can take action against unsafe products. Import Alerts and Warning Letters have been issued for non-compliant temporary tattoos and henna products. However, state and local authorities often oversee tattooing practices, leading to inconsistent safety enforcement.
Before using any temporary tattoo product:
Test it on a small area.
Check for ingredient listings.
Avoid products marketed as "black henna."
