Laser treatment of primary axillary hyperhidrosis: a review of the literature.

Abstract

Hyperhidrosis o`ccurs when the body produces sweat beyond what is essential to maintain thermal homeostasis. The condition tends to occur in areas marked by high-eccrine density such as the axillae, palms, and soles and less commonly in the craniofacial area. The current standard of care is topical aluminum chloride hexahydrate antiperspirant (10-20%), but other treatments such as anticholinergics, clonidine, propranolol, antiadrenergics, injections with attenuated botulinum toxin, microwave technology, and surgery have been therapeutically implicated as well. Yet, many of these treatments have limited efficacy, systemic side effects, and may be linked with significant surgical morbidity, creating need for the development of new and effective therapies for controlling excessive sweating. In this literature review, we examined the use of lasers, particularly the Neodynium:Yttrium-Aluminum-Garnet (Nd:YAG) and diode lasers, in treating hyperhidrosis. Due to its demonstrated effectiveness and limited side effect profile, our review suggests that Nd:YAG laser may be a promising treatment modality for hyperhidrosis. Nevertheless, additional large, randomized controlled trials are necessary to confirm the safety and efficacy of this treatment option.
