Pulsed dye laser followed by intradermal botulinum toxin type-A in the treatment of rosacea-associated erythema and flushing.

Rosacea is a common inflammatory skin disease characterized by erythema, episodes of flushing, and inflammatory lesions. It typically affects the face and is more prevalent among fair skin individuals affecting women more than men. Various treatments are available for rosacea with light-based therapies commonly used in the management of erythema. The use of intradermal botulinum toxin type-A has been reported to be beneficial in the treatment of rosacea-associated erythema and flushing with good results and a low side-effect profile. In this article, we present our experience on the successful combination of both pulsed dye laser and intradermal botulinum toxin type-A in erythema and flushing in 20 rosacea patients. In addition to subjective improvement, we measured the degree of erythema using a 3D Antera camera in order to quantify our results. We demonstrated high efficacy and satisfaction rate with this combined approach and a low side-effect profile. To our knowledge, the combination of laser and intradermal botulinum toxin in the management of rosacea has not been previously reported.
