Artificial colors used in cosmetics are basically synthetic colors. These are imitators of natural color that are derived from petroleum or coal tar sources. They are used to make cosmetics look somewhat 'pretty' and should be avoided. Before using a product it is important to look at the label to check for any FD&C or D&C label (F - food and D&C - drug and cosmetics). These labels represent synthetic colors and should not be used. They are believed to be carcinogenic, a skin irritant and are proven to be linked to Attention-deficit Hyperactivity Disorder (ADHD) mainly in children. A few examples include Green#3 (Fast Green) which can cause bladder and testes tumor and Yellow#5 (Tartrazine) which may trigger hyperactivity in children.
