Botox works by temporarily blocking the release of a neurotransmitter called acetylcholine, which is responsible for muscle contractions. When injected into specific muscles, Botox causes those muscles to relax, which can help reduce wrinkles and fine lines on the face or neck, or alleviate symptoms of certain medical conditions such as chronic migraines or muscle spasms.

Botox injections are performed by a trained medical professional and typically take only a few minutes to administer. The effects of Botox usually last for several months, after which the injection may need to be repeated to maintain the desired results. Botox is generally considered safe when used as directed, although there may be some mild side effects such as temporary swelling or redness at the injection site.


Botox was developed by a team of ophthalmologists named Dr. Alan Scott and Dr. Jean Carruthers. In the 1970s, Dr. Scott was researching a solution to treat crossed eyes (strabismus) and discovered that injecting a small amount of botulinum toxin into the eye muscles could temporarily relax them, effectively treating the condition. Dr. Carruthers, an ophthalmologist and dermatologist, later realized the cosmetic potential of this neurotoxin when she noticed its ability to reduce the appearance of wrinkles and fine lines.
