How to Treat Sweaty Underarms

If you suffer from hyperhidrosis, then you’re all too familiar with the impact it has on your daily life. If you suffer from excessive underarm sweating, also known as axillary hyperhidrosis, then you may even go to great lengths to conceal your sweat and sweat stains from those around you. Underarm sweat stains can be embarrassing and bothersome, especially in social situations. To conceal your sweat stains you may employ a variety of tactics, from wearing dark colors and carrying a change of clothes, to wearing bulky layers. Sound familiar? Well, it doesn’t have to be that way, as it is a highly treatable condition!


Hyperhidrosis is a condition that affects nearly 5% of the global population, with most patients reporting excessive underarm sweat. One of the most effective ways to treat axillary hyperhidrosis is through iontophoresis!

This technology works by directing a mild current through the skin, neutralizing the connections between the sweat nerves and sweat glands. For the vast majority of cases, this significantly reduces excessive sweating. In fact, studies have shown that tap water iontophoresis devices such as Dermadry are extremely effective in the treatment of excessive sweating. These studies report that the success rates of these devices can reach 93%, 98.5% and even 100% of patients treated for hyperhidrosis.


Iontophoresis is a non-invasive, drug-free, and needle-free treatment option. It is ideal for those looking for long-lasting dryness that antiperspirant sticks and creams just cannot provide. Due to its effectiveness and its limited side effects, it is also recommended over more dangerous and/or invasive treatment options such as medications, injections, and surgery.

Since its introduction as a treatment option for hyperhidrosis, iontophoresis has undergone many developments and improvements. Home-use devices, such as Dermadry, make treatment more convenient than ever before! There’s no longer a need to schedule appointments, as you can now build your own treatment schedule and get results from the comfort of your own home. Underarm treatment sessions are only 15 minutes and can provide up to 6 weeks of dryness! Following the initial treatment phase, treatments need to be maintained (as little as once every 2-3 weeks!) to maintain dryness.

Dermadry’s iontophoresis device is simple to set up and only requires access to an electrical outlet and some tap water. Dermadry is indicated for use by those 13 years and older to treat mild to severe primary palmar, plantar, and axillary hyperhidrosis.
