BTX muscle-relaxing injections: 

An extremely quick, safe, and effective treatment, BTX injections is the most common cosmetic medical procedure in the world. It works by injecting tiny doses of BTX into the muscles that cause crows feet, frown and forehead lines.  Over two weeks, following treatment, the muscles gradually relax and the lines smooth, providing a natural-looking result.  The common areas indicated are upper face lines and crow’s feet.  Dr Prendergast also uses this product to relax lines around the mouth, and for horizontal neck lines.
