How Does Pregnancy Affect the Skin?

Pregnancy is the happiest time for all women in their lifetime. A woman’s body goes through multiple changes during these 9 months of pregnancy.

Almost 90% of women experience skin changes during pregnancy. In addition, the changes in the skin experienced by each woman can be different. Because most pregnant women are not aware of these pregnancy changes, they are not ready to face these changes, so they are worried. This article contains information about the skin changes seen during pregnancy.
