Cosmetics and personal care products are substances that human beings have used for ages to beautify the appearance, clean, care and remove unpleasant odors from the body. In the first periods of the use of cosmetic products, its content consisted of plant extracts and vegetable oils. Years later, the use of chemical substances in the content has started to be preferred frequently in order to increase the absorption of cosmetic products from the skin and to extend the permanence period. Environmental agents are called teratogens that cause congenital anatomical anomalies in the embryo. The entry of harmful chemicals in cosmetic products into the human body occurs through skin absorption, mouth or inhalation. One of the most risky periods for the use of cosmetic products that contain a lot of toxic substances is the pregnancy period. Environmental chemicals in these products cause congenital anatomical anomalies and abortion in the fetus. Experimental studies on the teratogenic effect of cosmetic products on the fetus during pregnancy are very limited. For this reason, it was stated that the use of these products should be limited until it is determined that they are completely harmless. In this review, the effect of environmental chemicals in the content of personal care and cosmetic products, which are considered teratogens during pregnancy, on fetal health has been tried to be evaluated.
