Why pregnancy pigmentation occurs? And when does it go away?

Those skin pigmentations that accompany you during your pregnancy fear dark spots on your beautiful skin, although they are annoying and worrying for some pregnant women, but they are actually very natural changes that accompany 75% of pregnancies.
The cause of pigmentation is the rise in estrogen in the body, which leads to an increase in the activity of the cells that produce the melanin pigment in the skin. Pigmentation usually takes the form of a general darkening of the skin color with darkening more severe in some areas such as the armpits, pubic areas, upper thighs and nipples, and the color of existing birthmarks and freckles can increase. Before pregnancy, as well as scars.
About three quarters of pregnant women experience the formation of a dark line extending vertically from the navel to the pubic area called the “brown line.” Half of pregnant women develop melasma, which appears as large dark spots in the face on the sides of the cheeks, nose and forehead called “the mask of pregnancy.”
These pigment marks need several months to appear clearly, and they peak during the peak of pregnancy hormones secretion in the last three months of pregnancy.
Just as pigmentation is formed due to pregnancy hormones and takes months to appear, it disappears with the demise of pregnancy hormones after childbirth and needs months to disappear.
Do not be afraid if you notice strange strange colors on your skin, as you will quickly regain your luster after giving birth.
