Common skin conditions observed during pregnancy can be divided into three categories: hormone-related, preexisting, and pregnancy-specific. Normal hormonal changes as a result of pregnancy can cause benign (not cancerous) skin ailments. Preexisting skin conditions may change (improve or worsen) with pregnancy.

Striae gravidarum, or stretch marks, are caused by normal hormonal changes accompanying pregnancy.

Stretch marks occur when the body grows faster than the skin resulting in the breakdown of elastic fibers just beneath the skin. It is hard to determine who will develop stretch marks, but risk factors include family history of stretch marks with pregnancy, rapid weight gain, carrying multiples, carrying large babies, and being nonwhite. An array of creams and oils are used to prevent stretch marks; however, there is no scientific evidence that they are effective.
