BACKGROUND: Rosacea, a chronic inflammatory skin condition, is marked by enduring redness, visible blood vessels, and inflammatory eruptions in facial areas. Managing rosacea remains a persistent challenge for dermatologists, especially in cases unresponsive to conventional treatments. Injectable poly-d,l-lactic acid (PDLLA) has shown promise in treating erythema and telangiectasia associated with rosacea in addition to age-related concerns. Employing Mirajet, a laser-induced microjet system, for administering PDLLA is a novel and promising treatment for rosacea.
AIMS: We aimed to evaluate the efficacy and safety of injectable PDLLA delivered via a needle-free microjet system for managing rosacea.
METHODS: Four Korean women with persistent and refractory rosacea received five monthly sessions of PDLLA needle-free injections. Clinical assessments were conducted using the Clinician's Erythema Assessment and Patient's Self-Assessment (PSA) at baseline, 4 weeks post-treatment, and 22 weeks post-final treatment. Adverse events were monitored throughout the study period.
RESULTS: At 4 weeks post-treatment, both Clinician's Erythema Assessment and PSA scores indicated significant improvements in erythema that were sustained up to the 22-week follow-up. Patients reported high satisfaction with resolution of redness and improved skin texture. Mild swelling, redness, and petechiae were observed post-treatment but resolved spontaneously. No product-related adverse events were noted during the study period.
CONCLUSION: Injectable PDLLA delivered via laser-induced microjet injection demonstrated promising efficacy in improving rosacea symptoms and skin quality for up to 22 weeks without significant adverse effects. Larger randomized controlled trials are needed to confirm these findings and evaluate long-term safety and sustainability of outcomes.
