Quick Answer: Botox for underarm sweating is temporary (lasts 4-6 months), requires repeat treatments, and has minimal downtime. MiraDry uses microwave energy to permanently destroy sweat glands — one or two treatments, no repeat visits, but higher upfront cost and more significant post-procedure swelling and soreness. For men who sweat heavily and want a long-term solution, MiraDry wins on permanence; for men who want to test results before committing, Botox is the smarter starting point.
How Each Treatment Works
Botox for hyperhidrosis (excessive sweating) works by blocking the acetylcholine signals that tell sweat glands to activate. The same mechanism that relaxes facial muscles applies in the underarm — injected botulinum toxin prevents the nerve signal from reaching sweat glands, reducing sweat production by 80-90% in the treated area. The effect is temporary because the nerve eventually forms new signaling pathways. MiraDry is fundamentally different: it delivers controlled microwave energy into the dermis specifically at the depth where sweat glands live. The energy heats and destroys the gland tissue. Destroyed sweat glands don't regenerate — the treatment is permanent.

Search by Zip Code →Both treatments significantly reduce underarm sweating. Clinical data for Botox shows 80-90% reduction in sweat production in the treated area, lasting 4-7 months in most men. Clinical data for MiraDry shows 82-86% reduction in sweat production that is largely permanent — most patients need only one or two treatments. MiraDry also permanently reduces underarm hair and odor glands as a side effect (which many men consider a benefit). The key caveat: permanent doesn't mean complete. Some sweat glands may not be fully destroyed, and the body doesn't compensate by sweating more elsewhere (a common myth).
MiraDry cost: $1,500-3,500 per session (typically 1-2 sessions needed). Botox for underarm sweating: $500-1,200 per session, repeated every 4-6 months. At 2.5 sessions per year, annual Botox cost = $1,250-3,000. MiraDry breaks even in 1-2 years for men who currently treat with Botox.
Downtime and Recovery
Botox for underarm hyperhidrosis requires no downtime. You can return to work and normal activities immediately. Some men notice mild tenderness at injection sites for 24 hours. MiraDry has more significant post-procedure effects: swelling, soreness, and temporary skin sensitivity in the underarm area that can last 1-2 weeks. Most men take 2-3 days off from heavy upper-body exercise and work that requires raising the arms. Prescription-strength lidocaine is used during the MiraDry procedure to minimize discomfort. The recovery is manageable but real — this is not a lunchtime procedure.

For Botox hyperhidrosis treatment, most qualified aesthetic injectors can administer it — it requires understanding of the injection pattern (multiple small injections across the axillary vault, not just one or two). For MiraDry, only providers who have purchased and been trained on the specific MiraDry device can perform it; look for practices that list MiraDry as a named service and have significant device experience. Both treatments should be preceded by a consultation where the provider assesses the severity of your sweating and can advise on which approach is most appropriate for your specific situation.
