Content: Cosmetic injectables are substances purified from bacteria under strictly controlled conditions. When injected in minute quantities into the forehead, it decreases the strength of the underlying upper facial muscles. The result is a softening of frown lines, squint lines, nasal crunch lines and horizontal forehead wrinkles. More recently, Dr. Swift has modified the technique to allow for treatment of neckbands and droopy eyebrows. The effects of cosmetic injectables are usually first noticed 3-4 days after injection, and last for 4-6 months.
