This study compared the novel and conventional methods of PRP treatment for periorbital hyperpigmentation, and the results showed that the novel method is not inferior to the conventional method.
Background Platelet-rich plasma (PRP) has been found to be effective in treating periorbital hyperpigmentation (POH). PRP prepared by double-spin (DS) method and activated by calcium has been used conventionally. PRP can be prepared by single spin (SS) and activated at low temperature (novel method), but the evidence is limited. Objective To compare the novel and conventional PRP in the treatment of periorbital hyperpigmentation. Methods We selected 21 patients of POH and randomly divided the face into two halves. One-half of the face (group A) was treated with novel PRP (SS and low-temperature activation). The other half (group B) was treated with conventional PRP (DS and calcium activation). A total of 3 PRP injections were given at 4 weekly intervals. Patients were observed and assessed on 12(th) week by photography, dermoscopy, visual analog scale (VAS) score, and Dermatology life quality index (DLQI). Platelet counts and growth factors were assessed in PRP. Results Mean platelet count in novel and conventional PRP was 7.41 +/- 1.76 lacs and 8.17 +/- 2.23 lacs (p = 0.348). Mean photographic and dermoscopic assessment at the end of the study in group A and group B was 52.33 +/- 6.468 and 53.14 +/- 6.99 (p = 0.151). Change in VAS in groups A and B was 3.85 +/- 1.27 and 3.90 +/- 1.04 (p = 0.895). Levels of various growth factors assessed by ELISA did not differ significantly. There was significant decline in DLQI. Conclusion The novel method is not inferior to conventional method of PRP in the treatment of periorbital hyperpigmentation.
