Abstract

Background: Stretch marks are linear atrophic lesions on the skin caused by excessive skin stretching that exceeds the limits of elasticity. Stretch marks are more common in women. The appearance of stretch marks is influenced by genetic factors, hormonal factors, and mechanical factors. The INA score is used to assess the severity of stretch marks. A high BMI is associated with an increase in body fat, which causes excessive skin stretching and the appearance of stretch marks.
