The patient suffers from palmar-plantar hyperhidrosis, which can be treated using antiperspirants or botulinum toxin injections. Palmar-plantar hyperhidrosis is primarily about controlling sweat secretion and is caused by a disorder in the sympathetic nervous system function. In treatment, antiperspirants used mainly contain aluminum salt compounds, such as 20% aluminum chloride. It should be used according to the doctor's instructions, every three to five days. Typically, dryness and flaking of the skin occur after using the medication, and timely skin care is necessary. Botulinum toxin injections can also be used to treat palmar-plantar hyperhidrosis. Botulinum toxin can inhibit the action of acetylcholine at local nerve endings, which also has a therapeutic effect on local hyperhidrosis. Moreover, the effect lasts relatively long, maintaining about six months.
