Acetylcholine
Acetylcholine is a key neurotransmitter that transmits signals between nerve cells and between nerves and muscles, and controls muscle contractions.

Definition of acetylcholine
Acetylcholine is one of the most important neurotransmitters in the human body and plays a central role in signal transmission between nerve cells (neurons) and between nerve and muscle cells. It plays a key role in controlling muscle contractions, regulating heart function and the activity of the autonomic nervous system. Furthermore, acetylcholine influences cognitive processes such as learning, memory and attention.
Background
In the field of aesthetics, acetylcholine is particularly relevant in the context of the treatment of hyperhidrosis (excessive sweating). In this condition, sweat production is triggered by excessive activity of the acetylcholine system in the sweat glands. Botulinum toxin (Botox) is frequently used to block the release of acetylcholine at the nerve endings, thereby reducing sweat production.
Deficiency vs. hyperactivity
A deficiency or malfunction of acetylcholine can lead to neurological disorders such as myasthenia gravis (muscle weakness) or Alzheimer’s disease. Conversely, overactivity of the system can cause undesirable effects such as excessive sweating or muscle twitching (Spasticity). The targeted modulation of the acetylcholine system through medication or treatments such as Botox injections therefore offers a wide range of therapeutic options, both in medicine and in cosmetic surgery.

Treatment with acetylcholine
However, the treatment also carries risks such as temporary muscle weakness, allergic reactions, localised swelling or bruising at the injection site. In rare cases, the active ingredient may spread unintentionally, which can lead to difficulty swallowing, breathing problems or impairment of neighbouring muscles. It is therefore crucial that the treatment is administered professionally by experienced doctors and that patients are given comprehensive information about possible side effects and complications in order to ensure the safety and effectiveness of the treatment.
