If you notice any skin pigmentation on your face, palms, neck or underarms, don’t worry. This is fairly normal and is an effect of pregnancy hormones. Your skin will come back to its original glow once the hormones settle down.
You may also begin to notice darkening of nipples, scars, inner thighs and vulva. You will also notice a darkened line from your navel right up to your pubic bone. This is the the linea nigra or "dark line." In the meantime, if you do get self-conscious you can use a little concealer and feel better.
