Polydeoxyribonucleotide improves wound healing of fractional laser resurfacing in rat model.
Journal of Cosmetic and Laser Therapy : Official Publication of the European Society for Laser Dermatology 2017 Februrary
BACKGROUND: Polydeoxyribonucleotide (PDRN) is an active compound that can promote wound healing. PDRN stimulates wound healing by enhancing angiogenesis and increasing fibroblast growth rates. Laser skin resurfacing is a popular cosmetic procedure for skin rejuvenation. Despite excellent improvement of photo-damaged skin and acne scarring, it is accompanied with drawbacks, such as prolonged erythema and crusting.
OBJECTIVE: This study was designed to assess the effect of PDRN on wounds induced by fractional laser resurfacing.
METHODS: Twelve male rats aged 8 weeks were randomly assigned to the PDRN treatment group and the control group. Wounds were induced using a fractional ablative CO2 laser. The treatment group received daily injections of PDRN and the control group received injections of the vehicle. Wound healing assessed by clinical features and histopathologic findings.
RESULTS: The process of wound healing was faster in the treatment group than in the control group. In the histopathological examination, the granulation tissue thickness score of the treatment group was significantly higher than that of the control group. Results of immunohistochemical staining showed a marked increase of VEGF-positive cells and PECAM-1/CD31-positive microvessels in the treatment group.
CONCLUSION: PDRN may be a beneficial option to promote wound healing after laser treatment.
