There is usually no significant improvement in armpit odor after laser hair removal, and the really effective treatments are medication, physical therapy and surgery. Usually laser surgery only removes armpit hair, which can reduce parasitic bacteria, but generally armpit odor will not improve significantly. The pathogenesis of armpit odor is still unclear, and it is mostly considered to be related to factors such as heredity and parietal sweat glands, while the presence of a family history of armpit odor, strenuous exercise, heavy sweating, and spicy and oily diets can also induce or aggravate armpit odor. At present, the commonly used clinical treatments for armpit odor include medication (botulinum toxin injection), physical therapy (such as gold micro-needling, etc.), and surgical treatments (such as axillary deodorant extraction, minimally invasive axillary deodorantectomy, etc.). If the patient has a strong will to improve armpit odor, it is recommended that the patient go to a regular medical institution in time and take a reasonable way to treat armpit odor after laser hair removal.
