Safety of skin care products during pregnancy.

QUESTION: Many of my female patients complain about acne, unwanted hair growth, and other skin problems that have only developed since they became pregnant. Are products used for these types of benign skin conditions safe to use in pregnancy, as it is understandable that women want to look their best at this important time in their lives? ANSWER: With the exception of hydroquinone, which has a relatively high systemic absorption rate, and tretinoin, for which the evidence is controversial, these products act locally and therefore produce minimal systemic levels. Consequently, in most cases women can deal with these cosmetically unappealing skin conditions without compromising the safety of their unborn children.
