Reversibility of hyperhidrosis post axillary depilatory laser

Area of Science:

• Dermatology
• Aesthetic Medicine

Background:

• Laser-assisted axillary hair removal has been associated with hyperhidrosis (excessive sweating) and bromhidrosis (body odor).
• The reversibility of these side effects requires further investigation.

Purpose of the Study:

• To evaluate the reversibility of hyperhidrosis and bromhidrosis following laser-assisted axillary hair removal.
• To assess the efficacy of topical aluminum chloride treatment for persistent symptoms.

Main Methods:

• An observational, single-center cohort study followed 30 patients with newly reported hyperhidrosis/bromhidrosis post-laser treatment.
• Patients were monitored for 26 weeks for spontaneous symptom reversibility.
• Persistent hyperhidrosis was treated with topical aluminum chloride for 12 weeks and assessed using the Hyperhidrosis Disease Severity Scale (HDSS).

Main Results:

• Spontaneous reversibility of hyperhidrosis/bromhidrosis was observed in 20% of patients.
• A total of 23 out of 30 patients (76.7%) recovered normal axillary transpiration.
• The mean HDSS score was significantly reduced in patients receiving topical aluminum chloride treatment.

Conclusions:

• Axillary hyperhidrosis and bromhidrosis secondary to laser depilation appear to be reversible.
• Spontaneous recovery occurs in a subset of patients, while topical antiperspirants are effective for persistent cases.
