During pregnancy, you will notice the formation of a vertical dark line on your belly. Known as the linea nigra, it is a common phenomenon and is directly related to natural changes in the body of expectant mothers.
Causes
During pregnancy, pigmentation intensifies all over the body [1]. Under the effect of hormones, the skin begins to produce more melanin, which can accumulate to the point of creating dark spots in some areas, including the face, inner thighs, around the breast areolas, armpits, and abdomen [2].
Appearance
The dark line usually runs from the pubic bone to the navel or higher. The width and intensity of the line will vary from woman to woman [2]. Don’t worry if your line is barely visible, that’s normal too.
When does the linea nigra appear?
Increased pigmentation usually becomes noticeable in the early part of the second trimester and may become even darker in the final stages of pregnancy [3].
Skincare
There's no need to do anything to your dark line because it will disappear within a year after childbirth [2]. Avoid applying bleaching or lightening creams to your belly. Lightening agents can be dangerous for pregnant women [4]. However, make sure to protect yourself from the sun because the less the exposure to ultraviolet rays, the less intense the pigmentation will be [3].
