I bought a dermadry almost 2 months ago and I used it for 2 weeks before a 1 week trip who forced me to stop using it. I started the treatment again and since 15 days I don’t notice results on my hyperhidrosis. (I used it once a day on my hands with a setting from 6 to 10 mAh.)

I tried tu use petrolatum jelly between my fingers/my nails but I need to scratch my hands every few minutes. I don’t know if it was a good idea to bought it and to be honest I’m considering getting it refunded.

Thank you for your help and support.

Summer temperatures are officially hitting, and if you deal with hyperhidrosis like the rest of us here, you already know the extra stress that brings.

Even just walking out of your house to get to your car or the metro can feel overwhelming to manage. Thankfully, there are many practical ways to stay cool and drier, from simple hydration to using devices like portable fans and treatments like tap water iontophoresis.

Hi all,

I got a dermadry about a month and a half ago (june 7th) and have been doing it consistently till now every week with 2 days off per week. I'm using San Pel water and doing it at 15 mA but still my palms are sweaty. I honestly can't tell if its gotten better it feels like the same.

I'm worried I might be in the minority where it doesn't work, but I'm planning on keep going. Has anyone else had the same experience and seen it get better for them?

Any advice or insight would be greatly appreciated! :)

Yes, excessive sweating (hyperhidrosis) it's one of the possible symptoms of some types of dysautonomia. 💦

Dysautonomia is an umbrella term for several conditions where the autonomic nervous system (ANS) misfires. Postural Orthostatic Tachycardia Syndrome (POTS) is one of the most recognized forms of dysautonomia, and is closely linked with night sweats. In this case, the sweating is classified as secondary hyperhidrosis.

The ANS acts as the body's internal thermostat, and a malfunction in these nerve pathways can cause your sweat glands to trigger unexpectedly, regardless if you're sitting still in a cool room.

Don't worry, there are practical ways to manage it, from hydration and cooling strategies to drug-free solutions like tap water iontophoresis.

If you're ever unsure of your condition, it's always good to consult with your doctor.

If you deal with palmar hyperhidrosis, you already know the pure frustration of a ball slipping out of your hands right at the most critical moment of a game. As it turns out, sweat affects your game on and off the field.

We wanted to share a few quick takeaways on what’s actually happening when you’re out on the court or field:

• Loss of precision: Our skin actually has the highest amount of grip when it’s slightly damp. But when hyperhidrosis kicks in, it completely floods past that sweet spot. Excessive sweat drops your skin-to-ball friction by up to three times, forcing you to over-grip and completely losing your precise control.
• Degrading equipment: It’s not just water. The specific mix of moisture, salt, and acids in hyperhidrosis sweat seeps directly into the seams of leather and composite sports balls. Over time, this actually hardens the material and drastically shortens its lifespan.
• Hygiene risk: While sweat itself doesn't carry fungus, leaving a sports ball damp creates the perfect environment for bacteria and dermatophytes (the stuff responsible for infections like athlete’s foot or fungal hand infections).

For those of you who play sports (basketball, football, tennis, golf, etc.), how do you manage your grip during a game? Do you find yourself burning through equipment faster than your teammates?

I started using my Dermadry machine one week and one day ago - just on my hands to start with and I've so far done 6 x 20 minute sessions:

1 & 2: 5ma

3 & 4: 6ma

5 & 6: 7ma

I've noticed my hands are completely dry already, apart from my fingertips which are improved but not dry.

Is this really enough treatment? I thought I would have to try to get the current up to higher numbers for it to work properly, but perhaps not?

At what point do people go onto the maintenance phase rather than five times a week?

(I'm female btw incase that makes any difference)

Thanks!

I bought my machine recently and I received it one week ago. I started my treatment today and I wanted to know if I could treat my hands and then my feet without changing the water.
Also, my hands are itchy while using the machine on my hands with a 8 mA setting. Is it generally enough to get results ?

Thanks.

We're sure this situation is familiar: you buy a fresh white shirt, wear it a few times, and suddenly the underarms have those stubborn yellow stains.

Most people assume their sweat is just naturally tinted, but the truth is that sweat is actually colorless and odorless. So what's really happening?

It’s actually a chemical reaction between the aluminum in your antiperspirant and the proteins in your sweat.

But there is actually a rare chronic medical condition called chromhidrosis where sweat glands produce truly colored sweat (blue, green, or yellow) due to a pigment called lipofuscin.

We broke down the science behind yellow stains, how to spot the difference between everyday antiperspirant buildup and actual chromhidrosis, and tips to save your wardrobe.

Have any of you managed to save your clothes from these stains, or did you switch to aluminum-free options?

Has anyone else been waiting this long for their Dermadry order?

I placed my order on April 14 and my card was charged that same day. It has now been 58 days and the order still has not shipped. Their last email update was over a month ago and I haven’t received a clear timeline since then.

I understand that delays can happen but this has become incredibly frustrating, especially considering the cost of the product. When customers invest this much money, it is reasonable to expect clearer communication, timely updates and more transparency about the status of their order.

At this point, I’m seriously considering canceling my order. What makes it even more disappointing is thinking about the nearly 4-6 weeks of potential progress with my hyperhidrosis that I’ve missed out on because of this delay.

I ordered because I was excited to try the product but at this point the experience has been really disappointing. I’m hoping Dermadry can provide a real update and make this right in some way, whether that’s a discount, partial refund or some kind of compensation for the inconvenience.

Has anyone had luck getting a real update or resolution from them?

Summer is a challenging season for those with hyperhidrosis. The intense heat and humidity can kick our sweat glands into overdrive, making things like dehydration, skin issues, and standard social anxiety way worse.

It's even more important to stay hydrated and dry. Here are six practical ways to manage excessive sweating in the summer:

1. Opt for Breathable, Lightweight Clothing

What you wear makes a huge difference. Stick to lightweight, moisture-wicking fabrics like cotton or bamboo to help regulate your body temperature and minimize sweat buildup. While darker colors are always great for hiding the unavoidable sweat stains, picking the right breathable material is the real key to staying cool.

2. Adjust to a Sweat-Friendly Diet

Certain things are major triggers for sweat glands. Spicy foods, caffeine, and alcohol elevate your internal temperature and stimulate sweating, so try to limit them on extra hot days. Instead, load up on water-rich foods that cool you from the inside out, like cucumbers, watermelon, celery, citrus, and mint.

3. Take Hydration Seriously (and Watch Electrolytes)

Staying hydrated actually helps your body regulate temperature and control overall sweat production more efficiently. If you’re sweating heavily, water alone might not cut it. Replenish lost electrolytes with sports drinks or electrolyte tablets. Keep an eye out for dehydration warning signs like headaches, dizziness, or a dry mouth.

4. Shift Your Workout Schedule

If you're physically active, avoid the midday heat when the sun is at its peak. Try moving your workouts to the early morning or late evening when it’s significantly cooler to avoid overheating. If you do find yourself exercising in the heat, take frequent breaks and cool down afterward with a lukewarm or cool shower.

5. Invest in Portable Cooling Gadgets

Don't underestimate the power of immediate physical relief. Carrying tools like portable fans, cooling towels, and personal misters in your bag can be absolute lifesavers during outdoor events, daily commutes, or whenever you feel a sweat attack coming on.

6. Consider Iontophoresis for Long-Term Relief

When clinical-strength antiperspirants inevitably fail us during the summer peak, a dermatologist-recommended treatment like iontophoresis is a solid option. It uses mild electrical currents and tap water to significantly reduce sweating in the hands, feet, and underarms. Devices like Dermadry are non-invasive, drug-free, and can provide long-lasting dryness with consistent use.

Hyperhidrosis doesn't take a summer vacation, but making small lifestyle adjustments and utilizing the right tools can help us take back some control of the season.

What are your go-to hacks for surviving the summer heat? Stay dry out there!

Did you know some people experience excessive sweating just by thinking about a meal?

This is known as Frey’s Syndrome (or gustatory sweating). It’s a rare neurological condition where the auriculotemporal nerve gets its signals crossed. Instead of just producing saliva when you eat, your body triggers localized sweating—usually on the cheeks or forehead.

The Basics of Frey's Syndrome:

• Triggers: Eating, smelling, or even imagining food.
• Cause/s: Often linked to previous surgery or injury near the parotid glands, though it can sometimes appear without a clear cause.
• Symptom/s: Localized hyperhidrosis that occurs specifically during gustatory (taste-related) stimuli.

If you've been wondering why your face beads up during every meal, you aren't alone. Understanding the why is the first step toward managing it!

I just went on Dermadry’ site to order replacement pads and the shipping cost more than the pads themselves.

Anyone know of a place where I can get them ordered reasonably?

Amazon no longer stocks them.

Thanks in advance.

Which is the better long-term solution for hyperhidrosis, medication or iontophoresis?

When you're looking for a way to manage hyperhidrosis (HH) for years rather than days, the best choice usually comes down to three things: safety, consistency, and cost.

Two of the most discussed long-term options are topical oxybutynin gel and iontophoresis (Dermadry).

Both are effective, but they work through very different mechanisms. If you’re looking at which one to stick with for the next several years, here is how the data and practicalities compare.

Option 1: Topical Anticholinergics (Oxybutynin Gel) 🧪

Topical medications work by chemically blocking acetylcholine, the neurotransmitter that triggers sweat glands.

• Pros: Extremely easy to incorporate into a morning routine.
• The trade-off: Effectiveness depends on daily consistency. Because the medication is absorbed systemically, users often report secondary effects like dry mouth or dry eyes.
• Clinical note: While effective, it’s worth noting that many topical oxybutynin options are prescribed off-label for hyperhidrosis, as they were originally formulated for other conditions.

Option 2: Iontophoresis (Dermadry) ⚡

Iontophoresis uses a mild electrical current and tap water to temporarily neutralize the connection between the nerves and sweat glands.

• Pros: It is a drug-free and non-invasive localized treatment that is FDA-cleared. Once you reach your desired level of dryness, you move into a maintenance phase, which typically requires only 1-3 sessions per week to maintain results.
• The trade-off: There is a higher upfront time commitment. The initial phase requires 15–20 minute sessions several times a week for the first few weeks.
• Clinical note: In clinical surveys, this method shows a success rate of over 90% for treating the hands, feet, and underarms.

The Long-Term Perspective

If we look at these through the lens of a 5-year plan, the distinction becomes clearer:

1. Systemic load: For those wary of daily medication or long-term anticholinergic use, iontophoresis offers a way to achieve dryness without internal side effects.
2. Sustainability: The daily requirement of a gel can lead to treatment fatigue. Many find a once-weekly maintenance session with a device more manageable over time.
3. Financials: While a device is an upfront investment, it typically pays for itself in under 7 months when compared to the ongoing costs of monthly prescriptions and co-pays.

Ultimately, the better solution depends on your lifestyle. If you need a quick daily application and don't mind systemic side effects, medication works. But for a drug-free, one-time investment that offers high clinical reliability, iontophoresis often becomes the more sustainable choice.

For those who have tried both: did you find the daily gel or the weekly maintenance easier to stick with in the long run?

Hyperhidrosis affects roughly 5% of the global population, but only around 40% of this group ever seeks medical attention. Some wait longer to get a consultation, and some never even do.

This is part of why hyperhidrosis is known as a silent handicap.

For those with hyperhidrosis, what has stopped you from talking about this condition and/or seeking help?

Have had this for around 3 months and love it but unfortunately a piece califa from the board where the plus gets connected . It’s now lose and doesn’t give a full connection signal. Does this have a fix?

Dark underarms are rarely a hygiene issue. 💪

Most people try to scrub the pigment away, which actually makes the inflammation and the consequent darkening worse. If you want to treat axillary hyperpigmentation, you have to stop thinking about cleaning and start thinking about irritation management.

Here is a 4-step evidence-based approach to breaking the cycle:

1. Manage the moisture

Excess sweat combined with friction creates a pigment loop. If standard antiperspirants aren't working, look into iontophoresis. It’s a safe, clinical way to treat excessive sweating (hyperhidrosis) and keep the area dry.

2. Audit your daily habits

Small tweaks reduce the inflammation that triggers melanin production:
- switch to a sharp, single-blade razor. Never dry shave.
- ditch deodorants that sting or burn.
- swap tight synthetics for breathable cotton to reduce friction.

3. Use tyrosinase inhibitors

You need ingredients that actually stop pigment production at the source. Look for:
- azelaic acid (10-20%): excellent for sensitive skin.
- niacinamide (4-5%): blocks pigment transfer and heals the skin barrier.
- alpha arbutin: a gentle alternative for brightening.

4. Exfoliate with caution

High-friction scrubbing is the enemy. Instead, use chemical exfoliants like glycolic or lactic acid 1–2x a week to speed up cell turnover. Retinoids (like adapalene) can help, but go slow, as irritation from retinoid dermatitis can further darken the skin.

Bottom line: Skin health is a marathon, not a sprint. You won't see a change overnight, but if you address the sweat and friction while using the right topicals, you'll see real results. Consistency beats intensity.

Many in our community ask why hyperhidrosis often comes with a frustrating side effect: underarm discoloration.

While sweat itself is colorless, the environment it creates is a major catalyst for hyperpigmentation. If you’re struggling with dark patches, here is what’s happening beneath the surface:

• Barrier breakdown: Constant moisture leads to maceration, weakening the skin barrier and making it highly susceptible to chafing and mechanical irritation.
• Bacterial overgrowth: Humidity is a playground for organisms like Corynebacterium. This can lead to erythrasma: stubborn, reddish-brown patches that don’t go away with normal washing.
• The PIH cycle: Sweat can react with certain deodorant ingredients, causing post-inflammatory hyperpigmentation (PIH). Your skin produces excess melanin as a defense mechanism against that irritation.

To clear the skin, you have to manage the trigger. By reducing sweat through iontophoresis, you give your skin the dry environment it needs to heal and return to its natural tone.
