In the 1980s, it was discovered that a well-documented naturally occurring substance first described in medical journals in the late 1800s, had the ability, in therapeutic doses, to temporarily produce the cosmetic result of relaxing facial wrinkles and lines caused by years of repetitive and sometimes hyperactive contraction.
This substance, whilst normally quite toxic (widely known as botulinum neurotoxin since 1897, and produced by the bacterium Clostridium botulinum and several other strains of Clostridium) was found to have 8 serologically distinct types (Types A to H), and it was found that one type in particular (Type A) relaxes facial muscle contractions and allows the skin to become smooth again – resulting in a more youthful appearance.
Also well-documented and researched, this Type A serotype is today used in anti-wrinkle injections/treatments and is especially useful to treat “crow’s feet” around the eyes, horizontal forehead lines and frown lines between the eyes. Results are temporary, lasting for 3-6 months.
