    TLDR Most skin changes during pregnancy are harmless and moles don't significantly change, but many women experience pigmentation changes due to hormones and sun exposure.
    The document from January 2017 examined skin pigmentation changes during pregnancy, particularly challenging the belief that moles (melanocytic nevi) significantly darken and grow due to hormonal changes. Studies indicated that nevi do not substantially change during pregnancy, except for possible growth in areas like the breasts and abdomen due to skin expansion. The document also noted that up to 90.7% of Pakistani women experience pigmentation changes during pregnancy, with melasma affecting 50-70% of pregnant women. These changes are attributed to hormonal influences, ultraviolet radiation, and genetic factors. Preventative measures include sun avoidance and sunscreen use, while treatments for persistent pigmentation postpartum may involve bleaching creams, hydroquinone, and other methods, considering safety during pregnancy and lactation. The document emphasized that most pigmentary changes during pregnancy are benign and reassurance is often the best management strategy.
