Hormones. It may lighten a little after you give birth. But it won't go back to normal. At least that is what I experienced

Changes in the skin are common during pregnancy. Many of the changes are caused by the higher levels of hormones during pregnancy. For example:
You may notice a darkening or redness of skin in some places.
Stretch marks may develop from your increase in weight.
Your skin may itch and become red.
Small flaps of skin called skin tags may form.
Hair may grow on the face or chest.
Spider veins or varicose veins may develop.
Some normal changes in your skin and hair are described below. Be sure to talk to your healthcare provider if you notice any unusual skin changes or have any questions about caring for your skin.
Where does the skin get darker?
One of the changes you might notice early in your pregnancy is a darkening of the skin on or around your nipples. Later in your pregnancy, you may see a dark line on your skin that runs down your abdomen from your belly button to your pubic hairline. This line is called the linea nigra, or black line. You might also have blotchy brown spots on your forehead, nose, or cheeks, a skin change called melasma, chloasma, or the mask of pregnancy.
The inner thighs may become darker. Freckles, moles, and scars may also seem darker.
The darkening of the skin is caused by the increased amounts of hormones during pregnancy and an increase in the substance called melanin that is made by your body to give color to your hair, skin, and eyes.
Skin darkening is more common in darker-skinned women. Most of these changes will fade or go away after delivery. The skin darkening is made worse by exposure to the sun. Using sunscreen when you are outdoors may help prevent it. Do NOT use skin-bleaching treatments while your pregnant.
