Introduction: The goal of our prospective study was to assess the efficacy of the topical Platelet-rich plasma on reducing superficial perioral wrinkles and restoring the dermal matrix. Materials and methods: 50 women with moderate to severe perioral wrinkles were treated on the perioral area by a single session of fractional CO2 laser skin resurfacing plus intradermal injection of prp. 25 patients (group 1) applied topically prp twice a day for 12 weeks as post laser treatment. 25 (group 2) applied gentamicin and betamethasone twice a day for the first 7 days and then hyaluronic acid gel for the following 12 weeks. Results: In group 1, moisture (p < 0.001), amount of collagen fiber (p < 0.001) skin elasticity (p < 0.001), PSAl (p < 0.001) and SSAl (p < 0.001) improved significantly. In group 2 all the parameters investigated improved but did not reach significant difference. Discussion: Our medical device with a plasma-like formulation is able to maintain prp active for a period of 7 days so patients are able to apply topically growth factors at home. Conclusions: Our prospective study proves that the use of topical prp reduces superficial perioral wrinkles and restore dermal matrix when used at home for 12 weeks.
