At Skinoza Clinic, we understand that excessive sweating—especially in sensitive areas like beneath the breasts—can be distressing, uncomfortable, and socially limiting. This condition, medically known as inframammary hyperhidrosis, affects many women but is often underreported due to embarrassment or lack of awareness.
If you’ve tried everything from medicated antiperspirants to absorbent pads and lifestyle changes with little success, Botox injections under the breasts might be the solution you’ve been searching for. This article explores how Botox can treat inframammary sweating, how the procedure works, what results you can expect, and why Skinoza Clinic is a trusted provider for this innovative treatment. 
What Is Inframammary Hyperhidrosis?
Hyperhidrosis is a condition characterised by excessive sweating that goes beyond what is necessary to regulate body temperature. While it most coonly affects the underarms, palms, soles, and face, it can also occur in less commonly discussed areas—such as under the breasts.
Symptoms of inframammary hyperhidrosis may include:
-
Persistent moisture or dampness in the fold beneath the breasts
-
Skin irritation or rashes (intertrigo)
-
Fungal or bacterial infections due to prolonged moisture
-
Embarrassment in social or intimate settings
-
Damage to clothing or visible sweat marks
This condition may worsen in hot weather, during exercise, or under stress.
Why Does Sweating Happen Under the Breasts?
Sweating in this area can be caused by several factors:
-
Overactive sweat glands
-
Heat and friction caused by skin-on-skin contact or tight clothing
-
Hormonal changes
-
Obesity or large breast size, increasing moisture retention in the fold
While many women experience some degree of sweating under the breasts, hyperhidrosis refers to an abnormal level of sweating that significantly affects daily life.
Traditional Treatments for Under-Breast Sweating
Before discovering Botox as a treatment option, many women try:
1. Antiperspirants
Over-the-counter or prescription-strength aluminium-based products can reduce sweating temporarily but may irritate the skin or be ineffective in severe cases.
2. Powders and Absorbent Pads
These may help keep the area dry but can be uncomfortable and require frequent reapplication.
3. Oral Medications
Anticholinergics like glycopyrrolate may reduce sweating but often come with unwanted side effects like dry mouth or blurred vision.
4. Lifestyle Adjustments
Wearing breathable clothing, maintaining hygiene, and weight management can help reduce severity but often aren’t enough for those with moderate to severe hyperhidrosis.
Botox: A Breakthrough in Treating Inframammary Sweating
Botulinum toxin (Botox) is best known for its use in cosmetic wrinkle reduction, but it also has highly effective medical applications, particularly in treating excessive sweating (primary focal hyperhidrosis).
Botox works by blocking the nerve signals that stimulate sweat glands, effectively shutting down sweat production in the targeted area. This treatment has been approved by the FDA and is widely used for underarm sweating—and now, it’s becoming increasingly popular for treating under-breast hyperhidrosis. Botox can reduce sweating in treated areas by up to 80–90%, offering relief for 4 to 9 months.
How Does the Procedure Work?
Step-by-Step Botox Treatment for Under-Breast Sweating at Skinoza Clinic:
-
Consultation
You’ll meet with one of our experienced practitioners who will assess your symptoms, medical history, and suitability for the treatment. -
Mapping the Treatment Area
The skin is cleaned, and a starch-iodine test may be used to map out the areas of highest sweat concentration. -
Botox Injections
Using a fine needle, small amounts of Botox are injected into the skin beneath the breasts in a grid-like pattern. Most patients tolerate the procedure well, and topical numbing cream can be applied for comfort. -
Aftercare
You can resume normal activities immediately. Avoid vigorous exercise, hot showers, or tight bras for 24 hours.
What Results Can You Expect?
Most patients notice a significant reduction in sweating within 4 to 7 days, with full results typically seen after 2 weeks.
Benefits include:
-
Dryer, more comfortable skin
-
Improved confidence in social and intimate settings
-
Reduced skin irritation and infections
-
No visible scarring or downtime
The results usually last 4–6 months, and with repeated treatments, some patients notice longer-lasting effects.
Is Botox Safe for Use Under the Breasts?
Yes—when administered by a trained professional, Botox is considered safe and effective for use in multiple body areas, including the underarms, hands, feet, and under the breasts.
Clinical studies support the use of Botox for hyperhidrosis beyond the axillary (underarm) area:
Reference 1:
Hexsel et al. (2003) demonstrated that Botox effectively reduced sweating in various body areas, including off-label zones, with high patient satisfaction and minimal side effects.
Reference: Hexsel D, Dal’Forno T, Hexsel C. Botulinum toxin for the treatment of hyperhidrosis. Dermatol Clin. 2004;22(2):213–221.
Reference 2:
Naumann and Lowe (2001) reviewed the use of botulinum toxin for primary focal hyperhidrosis and concluded it is a safe, minimally invasive treatment with a strong efficacy profile.
Reference: Naumann M, Lowe NJ. Botulinum toxin type A in treatment of bilateral primary axillary hyperhidrosis: randomized, parallel group, double blind, placebo-controlled trial. BMJ. 2001;323(7313):596–599.
Although under-breast sweating is not yet an FDA-approved indication, Botox is increasingly used off-label for this purpose with excellent results.
