Platelet‐Rich Plasma Injection Combined With Q‐Switched Ruby Laser in the Treatment of Periorbital Hyperpigmentation

Background Periorbital hyperpigmentation is a prevalent skin condition that represents a large quantity of cases seen in cosmetic dermatology. Patients tend to be left with pigmentation after Q‐switched ruby laser treatment, especially the perioribital area. Aims The study is conducted to compare the effect of PRP injection combined with laser therapy versus laser alone for periorbital hyperpigmentation treatment. Patients/Methods In this single‐center, case–control study, 30 patients with periorbital hyperpigmentation were allocated to receive PRP injection injection after Q‐switched ruby laser or Q‐switched ruby laser only, followed by a 12‐week and 24‐week follow‐up visit. Visual analogue scale, Sadick tear trough rating scale, and patients' self‐evaluation were used to evaluate the therapeutic effect. Results The combined group achieved a better improvement in long‐term effect and had effect on facial rejuvenation. Patient satisfaction was higher in the combined group. Erythema and mild pain were the most common adverse reactions of both groups. Conclusions Combining with PRP injection can improve the therapeutic effect of Q‐switched ruby laser in treating periorbital hyperpigmentation and lessen the risk of post‐inflammatory hyperpigmentation, indicating a new option for POH treatment.
