Intradermal BTX-A injection is an effective treatment for intractable erythema and flushing in patients with refractory rosacea, with significant improvements in symptoms and quality of life. However, the effect tends to decrease after 6 months.
Introduction The persistent erythema and flushing seen in some cases of rosacea do not respond effectively to, or may easily relapse after, oral medication or light-based therapies (laser or intense pulsed light). Intradermal botulinum toxin A (BTX-A) injection can be used to treat intractable erythema and flushing, but studies with large samples and long-term observation have not been conducted to determine its effectiveness and safety. The aim of this study is thus to investigate the effective duration and safety of intradermal BTX-A injection for intractable erythema and flushing. Methods Sixteen patients with rosacea with erythema telangiectasia were injected with BTX-A at 1-cm intervals between each point. Clinician Erythema Assessment (CEA) scores were obtained at baseline and 1 month after injection. Flushing assessment and survey using the Dermatological Quality of Life Index (DLQI) questionnaire were conducted at baseline and at 1, 3, and 6 months after injection. Results At 1 month after injection, CEA scores revealed significant improvements in erythema and flushing; the results of the questionnaire on flushing and DLQI indicated that the improvement of flushing usually lasted for 3-6 months, but the effect decreased significantly at 6 months, and individual patients needed another treatment. Conclusions BTX-A significantly improves the symptoms and quality of life of patients with refractory rosacea with few adverse effects.
