You probably thought your pimple days were over. While the acne of pregnancy is rarely as severe as that of adolescence, you may need to return to some of your teenage cleansing rituals. Sometime in the second trimester a linea alba becomes a linea nigra, a dark line that is much more noticeable. In some women the line extends upward from the navel as well. The linea nigra is darker in darker-skinned women and disappears several months after delivery.
Dark areas become darker.
Little moles and freckles that existed prior to pregnancy may now become bigger and brown spots or birthmarks become browner. New moles may also appear. Red palms and soles. Even as early as the second month of pregnancy, the insides of your hands and the bottoms of your feet may itch and take on a reddish hue, called palmar erythema. The increased color is nothing more than a curiosity of pregnancy and will disappear a few months after delivery.
