The linea nigra is a thin, dark line that often runs from the top of your pelvis up to your belly button. Skin discolorations, particularly this one, are common during pregnancy and are nothing to be overly concerned about.
What causes it?
Much like chloasma, the linea nigra is a result of the overactive hormones in your body stimulating production of melanin, the substance primarily responsible for pigmentation in your body. As melanin production increases, you might start to see slight discolorations across your body, particularly the linea nigra. Women with darker skin are more likely to develop skin discolorations during pregnancy.
Tips?
Some believe that folate deficiencies are responsible for discolorations, so it’s a good idea to make sure your prenatal vitamin is rich in folic acid (the synthetic form of folate). The linea nigra can also be exacerbated by UV rays, so it’s better to be safe by applying sunscreen on the affected area when going outside on sunny days.
