Many sunless tanning products are available in the form of creams, gels, lotions, and sprays that are self-applied on the skin. Another option is the use of bronzers which are cosmetics that provide temporary effects such as 100% Herbal Instant Tan, an all natural ingredient bronzer. There is also a professional spray-on tanning option or “tanning booths” that is offered by spas, salons, and tanning businesses.
Spray tanning does not mean that a color is sprayed on the body. What is used in the spray tanning process is a colorless chemical which burns the dead cells located on the top layer of the skin, resulting in a brown color. The two main active ingredients used in most of the sunless tanners are dihydroxyacetone and erythrulose.
The U.S. Food and Drug Administration (FDA) has not approved the use of DHA spray tanning booths because it has not received safety data to support this specific use. DHA is a permitted color additive for cosmetic use restricted to external application. When used in a commercial spray tanning booth, areas such as the eyes, lips or mucous membrane are exposed to the DHA which is a non permitted use of the product.
