Rosacea is a chronic relapsing inflammatory skin disease, with a high prevalence among adults. Treatment of rosacea is difficult, with high rate of recurrence. Due to the strong anti- inflammatory and antibacterial effects of platelet rich plasma (PRP), it was used in the medicine for treating many inflammatory diseases. To evaluate the role of PRP injection in treatment of rosacea. The study was carried on 40 patients with rosacea. They were treated by PRP injection in right side of the face (group A) and platelet poor plasma injection in left side (group B). They underwent one session every 2 weeks for 3 months (6 sessions). The patients were assessed clinically before and after treatment by the rosacea grading scale. Skin biopsies were taken to evaluate the clinical results. There was a statistically significant decrease in rosacea grading scale after treatment with PRP injection, 50% of the patients showed excellent improvement and 50% showed good improvement. The improvement was significantly better in group A than B. There was marked decrease in inflammatory cells by hematoxylin and eosin stain, and decrease in expression of nuclear factor kappa βeta after treatment with PRP. PRP was effective and safe technique in treatment of rosacea and alternative to other systemic modalities, especially if they are contraindicated.
