Will MiraDry Help Reduce Underarm Odor Too?

​

Many people who struggle with excessive underarm sweating are concerned not only about the amount of sweat, but also about underarm odor (bromhidrosis).

Particularly during the summer months or stressful situations, some people feel that body odor becomes more noticeable. 

This can make social interactions uncomfortable, cause concerns about odor lingering on clothing, and lead to frequent use of deodorants throughout the day.

One of the most common questions we receive at HERSHE Plastic Surgery is: “If I get MiraDry, will it help reduce odor as well?”

Today, we'll explain how MiraDry may affect both sweating and underarm odor.

Why Does Underarm Odor Occur?​

​​​

What Is MiraDry?​​

MiraDry is a treatment that uses microwave energy, similar in principle to microwave technology, to selectively reduce sweat glands in the underarm area.

The procedure is performed without surgical incisions and is commonly considered for:

Excessive sweating (hyperhidrosis)

Underarm odor concerns (bromhidrosis)

Reducing sweat production

One of its notable characteristics is that the sweat glands that are treated do not regenerate, 

which is why many patients consider it a long-lasting or semi-permanent solution.

​Can MiraDry Help Reduce Odor?​​

The Short Answer: Yes, it may help.

MiraDry does not only affect eccrine sweat glands. It may also impact the apocrine sweat glands that contribute to odor production.

When the number of sweat glands is reduced, it may lead to:

Reduced sweat production

A less favorable environment for bacterial growth

Fewer odor-causing secretions

As a result, many patients report improvements not only in sweating but also in underarm odor.

In fact, some individuals say that their satisfaction with odor reduction was even greater than their satisfaction with sweat reduction.

Is One MiraDry Treatment Enough?​​

At HERSHE Plastic Surgery, we commonly explain that MiraDry is designed to provide long-lasting results, often after a single treatment.

In general:

Approximately 60–80% of sweat glands may be reduced after one session

Treated sweat glands do not regenerate

The procedure is not known to cause compensatory sweating in other areas of the body

However, individual responses and results can vary.

​Who May Benefit From MiraDry?

​

MiraDry may be considered by individuals who:

1. Experience excessive underarm sweating

2. Are concerned about underarm odor

3. Frequently rely on deodorants

4. Feel stressed by visible sweat stains on clothing

5. Prefer a non-surgical option

6. Find repeated Botox treatments burdensome

Post-Treatment Care?​​

​

Following the procedure, temporary symptoms may include:

Swelling

Tenderness

Warmth

Tightness or soreness

To support recovery, patients are often advised to:

Apply cold compresses

Maintain good hygiene

Avoid intense exercise temporarily

Get adequate rest

MiraDry is not solely designed to reduce underarm sweating.

Because it may also reduce the apocrine sweat glands associated with odor production,

it can be an option for individuals concerned about both hyperhidrosis and underarm odor.

Many patients experience high levels of satisfaction after a single treatment, 

making MiraDry a consideration for those whose daily lives are affected by underarm sweat and odor.

The most important step is determining whether the treatment is appropriate for your individual condition through a thorough consultation.​​
