Comparison Of Novel Aluminium Lactate Versus Aluminium Chloride-Based Antiperspirant In Excessive Axillary Perspiration: First Prospective Cohort Study

Aluminium chloride-based antiperspirants are an effective topical therapeutic option for mild to moderate states of excessive perspiration. Its use is primarily limited by the occurrence of skin irritation, especially in sensitive skin types. The objective of this study was to compare the antiperspirant efficacy and tolerability of a novel antiperspirant with 12.5% aluminium lactate, and a 12.5% aluminium chloride-based antiperspirant. This cohort study was conducted as a two-sided self-assessment comparison between both preparations in healthy volunteers to generate selfcare-related data. Almost half of the participants stated that aluminium chloride was more efficacious than aluminium lactate; 22% stated aluminium lactate was more efficacious than aluminium chloride; 28% observed no difference in the efficacy of both preparations (p = 0.04). However, 88% described greater tolerability with aluminium lactate (p < 0.0001). In this study, aluminium lactate showed significantly greater tolerability than aluminium chloride, although the latter tended to show slightly greater efficacy.
