Botox itself is a drug that dissolves fat in the subcutaneous tissues and is injected into the underarms by means of a syringe, which destroys the subcutaneous tissues in the underarms to a certain extent, thus destroying the sweat glands and preventing them from continuously secreting odor-bearing fluids. In general, there are no side effects of Botox for deodorant. If the medical staff does not operate properly and punctures the blood vessels in the armpit, it can lead to hematoma phenomenon. In this case, ice pack pressure should be applied immediately to relieve the symptoms. If the injection is too deep and injures the muscle layer of the armpit, it will lead to a strange sensation of lifting the arm, most of which can be relieved by itself in 2-4 weeks, and when the symptoms are more serious, it is necessary to seek medical treatment in time. Choosing professional and formal medical beauty institutions can effectively avoid side effects. In addition, the effect of Botox injection for deodorant odor is remarkable, but not permanent, usually the effect can be maintained in about 6 months, and the interval of 6 months between re-injections is appropriate. However, this condition is prone to recurring episodes of bad breath and is generally not used as a first-line treatment. The ideal treatment is to choose to use open surgery or minimally invasive surgery to destroy the underarm sweat glands.
