• One of the most common problems experienced with makeup is an allergic reaction. In many cases, a person doesn't know they are allergic to the makeup until after using it with adverse results. The chemicals can cause rashes, acne, itching or dryness, wherever the makeup has been applied. The reaction can be nearly undetectable to quite severe. Allergies can be determined by visiting a physician and completing a "patch test." During the test, the doctor applies certain chemicals to a small area of the skin, and then waits for a few days to see what reaction, if any, occurs. Once an allergy becomes apparent, consumers can avoid makeups that contain the problem chemical.
Acne
• Certain makeups clog pores more than others.
