Combined microneedling with topical application of platelet-rich plasma versus microneedling alone in the treatment of stria distensae: clinicopathological analysis

Background Striae distensae (SD) are common skin conditions. Objectives This study was done to test the hypothesis that ‘the use of microneedling (MN) before platelet-rich plasma (PRP) application will allow for deeper penetration and therefore, augment its efficacy in the treatment of SD.’ Patients...

Description
Summary:Background Striae distensae (SD) are common skin conditions. Objectives This study was done to test the hypothesis that ‘the use of microneedling (MN) before platelet-rich plasma (PRP) application will allow for deeper penetration and therefore, augment its efficacy in the treatment of SD.’ Patients and methods Forty patients with SD were divided into (i) Group I, the patients were treated with MN only, and (ii) Group II, the patients were treated with combined MN-PRP. The clinical improvement was evaluated by two dermatologists. Skin biopsies were obtained before and after therapy to examine immunohistological changes. Results As compared to the use of MN alone, therapy with combined MN-PRP was associated with: (i) a marked to the excellent improvement of the skin lesions of SD, (ii) a more significant deposition of collagen and elastic fibers, (iii) increased proliferative activity in the epidermis, and (iv) a decreased caspase-3 protein expression values in the epidermis. Conclusions This study proved that the combined MN-PRP is more effective than MN alone for the treatment of the lesions of SD. The underlying molecular mechanisms are open for future studies.
