1. Skin changes due to pregnancy
The skin and subcutaneous tissue stretch for months during pregnancy. After childbirth, they don’t always regain their initial firmness, which makes wrinkles more likely to form.
2. Accumulation of fat in the lower abdomen
This area naturally tends to store fat, especially after hormonal changes related to pregnancy.
3. Adaptation of internal tissues after surgery
A cesarean section involves incision of several layers of tissue; as it heals, small internal retractions can form, causing the skin to droop forward.
4. Fluid retention and the healing process
During the first few weeks and months, the abdomen is more swollen due to postpartum recovery; this can accentuate the appearance of the fold, which will resolve on its own over time.
