The cosmetic effect of BTX-A on wrinkles was originally documented by a plastic surgeon from Sacramento, California, Dr. Richard Clark, and published in the journal Plastic and Reconstructive Surgery in 1989. Since then, cosmetic use of botulinum toxin type A has become widespread with many patients viewing it as less intrusive and/or artificial than other types of plastic surgery. The results of cosmetic procedures vary but can last up to eight months. (Continued below)
Here is an actual Botox demo injection:
Side effects, which are generally minor and temporary, can be predicted from the mode of action (muscle paralysis) and chemical structure (protein) of the molecule, resulting broadly speaking in two major areas of side effects: paralysis of the wrong muscle group and allergic reaction. Bruising at the site of injection is a side effect not of the toxin, but rather the mode of administration. In cosmetic use, this can result in inappropriate facial expression such as drooping eyelid, double vision, uneven smile, or loss of the ability to close eyes. This will wear off in around six weeks. Bruising is prevented by the clinician applying pressure to the injection site, but may still occur, and will last around 7–10 days. When injecting the masseter muscle of the jaw, loss of muscle function will result in a loss or reduction of power to chew solid foods. All cosmetic treatments are of limited duration, and can be as short a period as six weeks, but usually one sees an effective period of between three and eight months. At the extremely low doses used medicinally, botulinum toxin has a very low degree of toxicity.
Other adverse events from cosmetic use include headaches, dysphagia, flu-like syndromes, blurred vision, dry mouth, fatigue, allergic reactions and swelling or redness at the injection site.
