Microneedle for Botulinum Toxin: A Randomized, Case-control, Single-blind Study to Assess Clinical Efficacy and Patient Satisfaction

This pilot study suggests that the MN device holds promise for optimizing the clinical results of botulinum toxin injections by controlling injection depth and enhancing patient acceptance and injection experience compared to standard needle injection. The absence of adverse events further supports the efficacy of MN for intradermal botulinum toxin use.
