This is also from the FDA website:
Using Sunless Tanners:
Before using a sunless tanning booth, ask the tanning salon these questions to make sure you will be protected:
- Will my eyes and the area surrounding them be protected?
- Will my nose, mouth, and ears be protected?
- Will I be protected from inhaling the tanning spray through my nose or mouth?
If the answer to any of these questions is "no," look for another salon. Otherwise you are putting yourself at risk for exposure to chemicals with potentially dangerous effects.
You should also take precautions if you're applying a self-tanner at home. Most self tanners contain the same DHA used in sunless tanning salons. Self-tanners are available in many forms, including lotions, creams, and sprays that you apply and let soak in to your skin. Follow the directions on the self-tanner label carefully and take care not to get the self-tanner in your eyes, nose, or mouth.
