SweatZap™ for Excessive Sweating in Beverly Hills

Antiperspirants work on the surface and neuromodulator injections interrupt the signal telling the glands to produce sweat, which is why both need repeating. SweatZap™ takes a different approach entirely, reaching the sweat glands themselves beneath the skin. For patients who have spent years managing hyperhidrosis rather than treating it, that structural difference is the point.

SweatZap™ was developed by Sam Assassa, MD, who has repeatedly brought new minimally invasive technique into practice, including the CosmoFaceLift™, Smart Liposculpt™, and EZ Lipo™. He founded Beverly Hills Aesthetics in 1995, is board certified in Internal Medicine, and is a member of the American Society for Laser Medicine and Surgery. Dr. Assassa also founded the American Association of Aesthetic Medicine and Surgery and has served as its President since 2006.

What Is SweatZap™?

SweatZap™ is a minimally invasive laser-based treatment designed to target and reduce overactive sweat glands beneath the skin. By delivering controlled energy directly to the glands, the treatment helps decrease sweat production in a precise and localized manner.

Unlike topical treatments or temporary solutions, SweatZap™ works at a structural level, addressing the source of excessive sweating rather than simply managing symptoms.

How SweatZap™ Works

A small incision of one to two millimeters is made under the arm and local anesthetic is placed directly into the treatment area. A fine cannula carrying the laser fiber is introduced through that incision and passed beneath the skin, where laser energy is delivered to the sweat glands themselves. The same energy seals small blood vessels as it works, which limits bleeding.

Treatment takes approximately one hour and is performed with you awake. Most patients report about two days of mild localized discomfort, with any bruising or swelling typically settling within forty-eight hours.

Because the treatment targets the glands themselves rather than interrupting the signal to them, a single session is intended to produce a lasting reduction rather than a result that needs repeating every few months. Sweat glands treated this way do not regenerate. Individual results vary, reduction rather than complete elimination is the realistic outcome, and some patients notice increased perspiration elsewhere on the body.

Why Patients Choose SweatZap™

Hyperhidrosis can impact daily life, from clothing choices to social interactions. While topical treatments, medications, or injections may help manage symptoms, they often require ongoing maintenance.

SweatZap™ offers a different approach by focusing on longer-term reduction of sweat production.

Patients often choose this treatment because it may provide:

• Significant reduction in underarm sweating
• A minimally invasive alternative to surgical procedures
• Minimal downtime with a quick return to daily activities
• A more lasting solution compared to temporary treatments

By addressing the underlying sweat glands directly, SweatZap™ is designed to deliver consistent and predictable results.

Why Experience Matters for SweatZap™

Energy-based treatments require precision and a strong understanding of anatomy to achieve optimal results while maintaining safety.

Dr. Assassa’s experience includes:

• Decades of work in minimally invasive and laser-based procedures
• Early adoption of advanced liposculpting technologies
• Leadership in aesthetic medicine and physician education
• A technique-focused approach that prioritizes accuracy and consistency

This level of experience is particularly important when working beneath the skin, where controlled energy delivery must be carefully applied to avoid irregularities or unnecessary tissue trauma.

Personalized Treatment Planning

Not all cases of excessive sweating are the same. The severity, location, and underlying causes can vary between patients.

At Beverly Hills Aesthetics, each treatment plan is customized based on:

• The area affected (most commonly underarms)
• The severity of sweating
• Previous treatments and response
• Individual goals and expectations

This personalized approach helps ensure that treatment is both effective and aligned with long-term results.

SweatZap™ Risks and Safety

This is a minimally invasive procedure performed under local anesthesia and it carries real considerations. Expected effects include mild discomfort, bruising, swelling, and tenderness in the treated area for a few days. A small mark remains at the incision site.

Risks include infection, bleeding, prolonged swelling, changes in skin sensation in the treated area, and thermal injury associated with the laser component. Compensatory sweating, meaning increased perspiration elsewhere on the body, is a recognized consideration in the treatment of hyperhidrosis and is worth discussing at consultation.

Individual results vary and no outcome can be guaranteed.

Frequently Asked Questions About SweatZap™

What areas can SweatZap™ treat?

SweatZap™ is most commonly used for underarm sweating, though other areas may be evaluated during consultation.

How is SweatZap™ different from injections?

Injections temporarily block the signals that trigger sweat glands, while SweatZap™ targets the glands themselves.

Is the procedure painful?

The treatment is performed with local anesthesia, and most patients experience minimal discomfort.

How long do results last?

SweatZap™ is designed to provide long-term reduction in sweating, though results may vary by individual.

Is there downtime after treatment?

Downtime is minimal, and most patients return to normal activities shortly after the procedure.

Take Control of Excessive Sweating with a Long-Term Solution

Excessive sweating can be difficult to manage with temporary treatments alone. SweatZap™ offers a more advanced approach by targeting the source of the problem with precision and minimal disruption to daily life.

With decades of experience, international recognition, and a commitment to minimally invasive innovation, Dr. Sam Assassa provides a trusted option for patients seeking a more lasting solution to hyperhidrosis.
