Aesthetic treatments for hyperhidrosis (excessive sweating) primarily focus on blocking sweat gland activity, offering both temporary relief and long-lasting, potentially permanent, solutions.
The main non-surgical aesthetic therapies include:
Injectable Treatments
Botulinum Toxin Injections (e.g., Botox): This is a widely used and highly effective treatment, considered a gold standard for focal hyperhidrosis.
Mechanism: Injected into the affected area (underarms, palms, feet, forehead), it temporarily blocks the nerve signals that stimulate the sweat glands, significantly reducing sweat production.
Effectiveness: Studies show an 80-90% reduction in sweating, with a single treatment lasting anywhere from 4 to 12 months.
Procedure: A quick, in-office procedure involving multiple small injections. Topical numbing creams can be used for comfort.
Medicare in Australia: Medicare rebates are available for eligible patients with severe axillary (underarm) hyperhidrosis who have not responded to or are intolerant of strong antiperspirants, making the out-of-pocket cost more affordable.
Energy-Based Procedures
Microwave Therapy (e.g., miraDry): This non-invasive procedure offers a more permanent solution for underarm sweating.
Mechanism: A handheld device delivers controlled electromagnetic energy to the underarm area, heating and permanently destroying the sweat glands.
Effectiveness: Most patients experience a significant and lasting reduction in sweat and odor after one or two sessions, as destroyed glands do not regenerate.Note: This is an expensive treatment and not typically covered by Medicare or private health insurance in Australia.
Other Non-Surgical Options
Iontophoresis: This is particularly effective for hyperhidrosis of the hands and feet.
Mechanism: The affected areas are submerged in a pan of tap water through which a mild electrical current is passed. This temporarily blocks the sweat glands.
Procedure: Requires multiple sessions per week initially, tapering off to maintenance treatments once a week or month. Devices are available for home use with a prescription.
Prescription Topical Treatments: Stronger antiperspirants containing high concentrations of aluminum chloride (e.g., Drysol, Xerac AC) or prescription creams and medicated wipes (e.g., Sofdra gel) are often the first line of treatment before proceeding to more advanced therapies. A consultation with a dermatologist or cosmetic physician is essential to determine the most suitable treatment plan based on the severity and location of the hyperhidrosis.
