Serious problems from cosmetic use are rare, but sometimes problems arise with specific products. For example, FDA warned consumers about the danger of using aerosol hairspray near heat, fire, or while smoking. Until hairspray is fully dry, it can ignite and cause serious burns. Injuries and deaths have occurred from fires related to aerosol hairsprays. The most common injury from cosmetics is from scratching the eye with a mascara wand.
Eye infections can result if the eye scratches go untreated.
Such infections can lead to ulcers on the cornea, loss of lashes, or even blindness. To play it safe, never try to apply mascara while riding in a car, bus, train or plane. Sharing makeup can also lead to serious problems. Washing your hands before using makeup will help prevent exposing the makeup to bacteria. Artificial nails can be a source of problems, especially when not applied correctly.
