How does Botox work?
Botox can erase wrinkles and prevent new ones from forming in the treated area. Botox is a toxin that paralyzes the muscles. When injected carefully and correctly, it weakens the muscles of the face that pull the skin when you make certain facial expressions. Exaggerated facial expressions cause folds in the skin, and over time, those little folds stay instead of springing back when you relax your face. By preventing those folds, Botox prevents wrinkles in the treated area for a period of months to years at a time (depending on many factors.)
When Botox is not performed properly, the muscles become "frozen" instead of just weakened, and the patient will not be able to make normal facial expressions.
Beware any cosmetic surgeons offering cheap prices for Botox--this indicates that they may be watering down the product or injecting something else that will not give good results.
