Facial lines are caused by the repeated use of facial muscles in a particular manner. Expressions such us squinting, frowning and smiling, caused by movement of the muscles under the skin, tend to create wrinkle and folds in the skin. The use of Botulinium toxin Type A (Botox) for the reduction of facial lines, is the most popular cosmetic treatment world-wide. Botox has been used in medicine for other indications for many years. Even very young children are treated for squints and nervous ticks with Botox injections. The substance cannot cause any permanent damage or travel within the body since it attaches itself to the target muscle and cannot migrate from there.
