Botox nasal spray (for hay fever) uses Botox’s ability to block the release of the neurotransmitter (acetylcholine), suppressing the function of the nerves (parasympathetic nerves) in the mucous membrane of the nose, resulting in pollen symptoms such as runny nose and itchy eyes. It is a treatment that reduces the symptoms of the disease. Treatment is possible even after the symptoms of hay fever appear, and by simply injecting a medicinal solution into the nasal cavity, the unpleasant symptoms of hay fever will subside from the day of the treatment. Because you don’t wear a mask, you don’t have to worry about your makeup coming off, and you don’t get the dry mouth and nose, drowsiness, or sluggishness that is characteristic of nasal inflammation drugs, which can interfere with daily life such as working, studying, or driving a car. No worries. It’s effective several hours after the treatment, so it’s also recommended before a wedding or important presentation.
