It’s a sweltering summer afternoon and the air feels thick with humidity. As you step outside, beads of sweat immediately form on your forehead and trickle down your back. For many, this is just an inconvenient side effect of the heat, but for those suffering from hyperhidrosis, or excessive sweating, this is a daily struggle that can turn even the simplest—and most enjoyable—warm-weather activities into a challenge.
Hyperhidrosis affects millions and can be particularly brutal during hot, humid months, as well as on days when your body doesn’t even need to cool down. But the season of fun in the sun and every month thereafter doesn’t have to be synonymous with sweat. To help you stay dry and comfortable all year-round, we consulted three top dermatologists who shared their best advice on managing sweat and surviving this oppressively hot summer weather.

How do I know if I have hyperhidrosis?
Hyperhidrosis is characterized by excessive sweating that exceeds what is necessary for normal body temperature regulation. It can affect various parts of the body, including the underarms, palms, feet and face. According to New York dermatologist Brendan Camp, MD, “Axillary hyperhidrosis can be treated with topical and oral medications, as well as in-office treatments. Understanding the nature of this condition is the first step towards effective management.”
What lifestyle changes can I make?
If you’re dealing with hyperhidrosis, consider tweaking some of your daily habits. For starters, be mindful of the foods and drinks you consume. “Spicy foods, caffeine and alcohol can exacerbate sweating,” explains Dr. Camp.
Drinking more water should also be on the menu, says New York dermatologist Morgan Rabach, MD. To counteract constant sweating, staying well-hydrated is essential. “Hydration plays a key role in managing hyperhidrosis,” she notes.
Additionally, consider what you’re wearing before you leave the house. Opting for loose-fitting, breathable materials such as cotton, linen and moisture-wicking fabrics can significantly impact your comfort. Commack, NY dermatologist Lauren Penzi, MD, says, “These fabrics allow your skin to breathe and reduce the amount of sweat that gets trapped against your body.”
Lastly, quitting smoking can also have a positive effect on your symptoms. “Quitting can help alleviate some of the symptoms associated with hyperhidrosis,” says Dr. Camp. By incorporating these lifestyle changes, you can better manage your sweat and overall comfort.
Which products should I buy?
While swiping on some deodorant may work for some, Dr. Rabach says that simply using an antiperspirant isn’t enough; it’s also crucial to apply it correctly. “Daily use of antiperspirants, particularly those with aluminum-based compounds, is recommended,” she says. “Applying them at night allows the product to effectively block sweat glands while you sleep.”
What professional treatments will help stop the sweat?
For those grappling with more persistent and severe cases of excessive sweating, in-office treatments can provide longer-lasting relief. Below are some of the most effective options available.
Underarm Injections
One of the most effective in-office treatments for hyperhidrosis involves neurotoxin injections, such as Botox. “Neurotoxin injections can inhibit the release of neurotoxins that stimulate the sweat signal, providing relief for three to six months,” Dr. Camp explains. This treatment works by blocking the release of acetylcholine, a chemical messenger that triggers sweat production. Dr. Lauren Penzi adds, “Botox is injected into the area of concern, usually the underarms, palms, or soles, and it takes about one to two weeks to see the full effects. The result is a significant reduction in sweating, making daily life much more comfortable.”
RF Microneedling
While radiofrequency microneedling might not be the first treatment that comes to mind for underarms—it’s more commonly used for acne scars, skin tightening, and evening skin texture—it’s also worth considering for hyperhidrosis. “Radio-frequency microneedling can be used to heat and destroy sweat glands in the underarm area,” says Dr. Camp. The process involves creating microscopic injuries in the skin with fine needles, which then deliver radio-frequency energy deep into the tissue. This dual-action approach reduces sweating and improves the skin’s texture and appearance. It’s a more permanent solution to excessive sweating while smoothing the underarm area.
Miradry
For those seeking a non-invasive procedure, Miradry is an excellent option. “Miradry uses microwave energy to destroy sweat glands,” explains Dr. Morgan Rabach. This treatment is particularly appealing because it involves no incisions and minimal downtime. The microwave energy targets and eliminates the sweat glands in the underarms, significantly reducing sweating in the treated area. Patients typically see immediate and lasting results after just one or two sessions, making it a popular choice for long-term sweat reduction.
Iontophoresis
A lesser-known but effective treatment, iontophoresis is a good option for those who suffer from palmar and plantar hyperhidrosis, which affects the hands and feet. “Iontophoresis works by delivering a mild electrical current through water into the skin’s surface,” says Dr. Penzi. The treatment is done using a special device where the affected hands or feet are submerged in water. Then, a mild electrical current passes through the water to reduce sweat production by temporarily blocking the sweat glands. Regular sessions can provide significant relief, making everyday activities more manageable.
Can I just take a pill?
In some cases, oral medications can be an effective way to manage hyperhidrosis. “Oral medications like glycopyrrolate can be used to treat hyperhidrosis when it affects multiple body parts,” says Dr. Camp. These medications work by inhibiting the action of neurotransmitters that stimulate sweat production. While effective, they can have side effects, so discussing the benefits and risks with your dermatologist to determine if this treatment is right for you is essential.
Hyperhidrosis: The TLDR
Managing hyperhidrosis might feel like a burden, but our experts stress that it may require a combination of all of the above, effective products and possibly professional treatments. Remember to consult with a board-certified dermatologist to find the best solution tailored to your unique needs. With the right proactive approach, you can stay cool, calm, and collected all summer long.
