In general, the effect of laser treatment for axillary odor is relatively good, but the specific outcome varies from person to person and there is a certain possibility of recurrence. Laser treatment for axillary odor is a non-surgical method that utilizes the thermal energy of the laser to target the apocrine glands under the armpits, reducing or eliminating the odor by destroying the sweat gland structures. Compared with traditional surgical excision, this method offers advantages such as minimal invasiveness and faster recovery, although its effectiveness and long-term results may vary depending on individual circumstances.

Laser treatment also has certain limitations. For patients with severe symptoms, extensive and deeply located apocrine glands, the laser may not completely destroy all the sweat glands, resulting in suboptimal treatment outcomes and potential recurrence. The effectiveness of laser treatment also depends on factors such as the number of treatment sessions, the skill of the operator, and the sophistication of the equipment used. Insufficient treatment sessions or improper operation may also affect the therapeutic outcome.

Patients should first visit a hospital for a thorough evaluation. The doctor will comprehensively assess factors such as the severity of the axillary odor and the patient's individual physical condition to determine the most suitable treatment plan. After laser treatment, proper post-treatment care is necessary, including keeping the treated area clean, avoiding manually peeling off scabs, and refraining from using irritating skincare products.
