Facial expressions such as smiling, squinting, or frowning cause the appearance of frown lines and crow’s feet to become more prominent due to repetitive movements of the underlying facial muscles. The constant stretching and pulling of the skin combined with the decrease in your skin’s strength and elasticity associated with aging, increases the appearance of wrinkles and fine lines as we get older. The naturally derived neuromodulators, Botox® and Xeomin® are two of the leading treatments in temporarily smoothing out these existing creases and preventing their occurrence and/or promoting the softened appearance in the future.
