Striae distensae, more commonly known as stretch marks, are dermal scars with flattening and atrophy of the upper skin layer. Commonly seen in adolescents and young adults, they are thought to be caused by continuous and progressive stretching forces to the skin.
There are numerous clinical situations in which they arise including mechanical stress such as that caused by sudden weight gain, corticosteroid therapy, Cushing’s syndrome, infections, and also from hormonal factors during puberty and pregnancy. Multiple treatment modalities have been tried with variable results and generally the treatment of cosmetically distressing stretch marks has been variable.
Recently Platelet Rich Plasma (PRP) therapy has been studied for improving the appearance of stretch marks and the overall skin health, with positive results.
