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.
