Pregnancy stretch marks may fade and subside after delivery, or they may persist. Many women are prone to spotting after pregnancy. The main reason for considering this is that the hormone level in the body changes after pregnancy, which may cause the phenomenon of melanin precipitation, leading to skin spots. This symptom may be aggravated if you usually do not pay attention to sun protection and are often exposed to ultraviolet rays. After delivery, the hormone level in the body returns to normal and stretch marks may gradually fade away or become lighter. However, everyone has a different skin type and stretch marks may persist in some women after delivery due to their physical condition. Stretch marks generally do not affect your health, but if you feel that they affect your appearance, you can go to the dermatology department of a hospital after delivery and take the doctor’s advice to treat them.
