How are Hyperhidrosis and Bromhidrosis Treatments Applied with Laser?


Excessive sweating (hyperhidrosis) and bad body odor (bromhidrosis) are dermatological problems that seriously affect individuals' social life, self-confidence and quality of life. Among the treatment options developed for these two conditions today, laser technologies are increasingly gaining attention and offer promising results. So, how effective is laser hyperhidrosis and bromhidrosis treatment? Which laser systems are preferred? Is it safe?

What is Hyperhidrosis and Why Does It Require Treatment?
Hyperhidrosis is a condition of involuntary and above-normal sweating that develops as a result of excessive activity of the eccrine sweat glands in the body. It is most commonly seen in areas such as the armpits, palms and soles of the feet and is mostly triggered by emotional stimuli. The severity of sweating directly affects the daily lives of patients and can lead to loss of self-confidence and social isolation.

The frequency of occurrence in society varies between 0.6% and 2%. Therefore, the need for effective, comfortable and permanent treatment methods is great.

What is Bromhidrosis? What is the Difference with Hyperhidrosis?
Bromhidrosis (osmidrosis) is a condition characterized by an unpleasant body odor that usually develops in areas where apocrine glands are dense, such as the armpits. It is often seen together with hyperhidrosis. A bad odor occurs especially when the sweat produced by the apocrine glands interacts with bacteria on the skin surface.

Bromhidrosis can cause more loss of quality of life than hyperhidrosis. It can stain clothes and create the need to constantly shower or change clothes.

How Sufficient Are Classical Treatment Methods?
The following methods are generally used in the treatment of hyperhidrosis and bromhidrosis:

Topical agents (such as aluminum chloride hexahydrate)

Botulinum toxin (sweating botox)

Iontophoresis and psychotherapy

Anticholinergic systemic drugs

Surgical treatments (sympathectomy, curettage)

However, these methods may not be sufficient for every patient. For this reason, laser treatments have been increasingly preferred in recent years.

Laser Hyperhidrosis Treatment: Which Systems Are Used?

Nd:YAG Laser (1064 nm)
It is one of the most commonly used lasers in the treatment of hyperhidrosis. Clinical studies have shown that Nd:YAG laser is an effective and safe option, especially in patients with underarm hyperhidrosis. Sweat glands are targeted and destroyed with subdermal application.

The Laser Assisted Reduction of Axillary Hyperhidrosis (LARAH) method is applied with a 1064 nm Nd:YAG laser and aims to destroy apocrine glands by causing minimal damage to the tissue.

Diode Laser (924/975 nm and 800 nm)
Diode laser systems can be used both alone and in combination with curettage. According to research, the success rate is higher, especially in combined applications. Results that continue to be effective for 1 year have been reported.

Laser Epilation and Hyperhidrosis: A Dual Relationship
Interestingly, it has been reported that hyperhidrosis may develop after laser epilation in some cases. However, in a study conducted by Letada and his colleagues, it was stated that long-pulsed Nd:YAG laser both reduces hair and provides a decrease in hyperhidrosis complaints. In other words, laser treatment applied with the right parameters can provide double benefits.

What is the Effect of Laser in Bromhidrosis Treatment?
CO₂ Laser
CO₂ laser acts by vaporizing the subcutaneous tissue, especially the apocrine sweat glands. In studies conducted since 1997, CO₂ laser and surgical resection have been compared and it has been reported that laser causes fewer complications. Stitching time is shorter and the healing process is more comfortable.

Nd:YAG Laser and Lipolysis Methods
Nd:YAG lipolysis lasers operating at a wavelength of 1,444 nm are effective in eliminating bad odor by providing subcutaneous coagulation. It stands out as a promising method in bromhidrosis thanks to its small scar, fast healing and minimally invasive nature.

Who is Suitable for? Who Should Pay Attention?
Laser treatment can be an effective option especially for individuals who are resistant to topical and systemic treatments, do not want surgery, and experience mild to moderate hyperhidrosis or bromhidrosis. However, it should be noted that some laser systems may be inadequate in advanced cases.

Are There Complications and Risks?
Although laser treatment is generally safe, the following side effects may be observed in some patients:

Superficial burns

Skin erosion or necrosis

Rarely, permanent scarring

Temporary hyperpigmentation

Under the supervision of a specialist dermatologist, these risks can be minimized with the appropriate device and technique.

Conclusion: Is Laser the Treatment of the Future in Hyperhidrosis and Bromhidrosis?
Current data show that laser technology is an effective, safe method for the treatment of hyperhidrosis and bromhidrosis, and increases patient comfort. Being less invasive compared to surgery, short recovery time and aesthetic advantages make laser attractive.
