Answer :
"Botox injections are smooth facial wrinkles because Botox is an acetylcholine antagonist which blocks the underlying facial muscles."
Botox, the trade name for botulinum toxin, is neurotoxic protein which is produced by the bacterium Clostridium botulinum. When injected into specific facial muscles, it acts as an acetylcholine antagonist, meaning it interferes with the neurotransmitter acetylcholine.
Acetylcholine is the neurotransmitter which plays a crucial role in muscle contraction. It is released by nerve cells (neurons) at the neuromuscular junction, where nerves connect to muscle fibers. The binding of acetylcholine to receptors on the muscle cell membrane triggers muscle contraction.
By acting as an acetylcholine antagonist, Botox blocks the release of acetylcholine from the nerve endings at the neuromuscular junction. This prevents the communication between the nerves and the muscle cells, leading to temporary muscle paralysis or weakness. When the underlying facial muscles are relaxed, the overlying skin becomes smoother, and wrinkles caused by repeated muscle contractions (e.g., frown lines, crow's feet) are reduced or diminished.

Answer:
Botulinum
Explanation:
Botox is used cosmetically to remove wrinkles and to treat certain muscular conditions. It is made from Botulinum neurotoxin obtained from the bacteria Clostridium botulinum. It is a very powerful neurotoxin but in Botox procedure it is used in extremely small concentration so it does not cause harmful effects. Botox process usually lasts for four to six months.
Botulinum acts as acetylcholine antagonist and inhibits the release of acetycholine neurotransmitter at the neuromuscular junction. This inhibits the signalling between motor neurons and facial muscles. As a result, the facial muscles are not able to contract and hence wrinkles are not formed on skin.
