Changes in hormone levels during your pregnancy may cause some temporary skin problems. Some pregnant women get brownish, uneven marks around their eyes and over the nose and cheeks. This is called chloasma. Being in the sun tends to increase these marks, so wear sunscreen and a hat when you are outside in the sun. The marks will fade or disappear after the baby is born.

Many women will have a dark line that starts above the navel and extends down to the pubic area. This line is called linea nigra. It will fade after delivery.

Many pregnant women develop reddish streaks or stretch marks as the abdomen and breasts grow. These marks are caused by the skin stretching to make room for your growing fetus. There is no way to prevent stretch marks during pregnancy, but they may fade slowly after pregnancy.

Two skin conditions which often appear together are redness of the palms and spider veins (small, red spots on the skin with lines branching out). These also will fade or lessen after your baby is born.

Acne may develop during early pregnancy, especially in women who often get pimples before their periods. The best way to treat mild acne is by washing your face with a mild cleanser several times a day. Do not take tetracycline (an antibiotic sometimes prescribed for acne) during your pregnancy.

Many women notice that their hair is thicker during pregnancy, while others find their hair becomes thinner. A few weeks after delivery, you may lose large amounts of hair, but your hair will soon return to its regular growing cycle.
