HOW DO WRINKLES FORM?
Dynamic wrinkles are different from wrinkles caused by sun damage or the loss of collagen and elastin in your skin, which we call static wrinkles. Static wrinkles are visible even when your face is at rest.
Dynamic wrinkles are those that appear when you make facial expressions, like frowning or squinting. Because Botox blocks the nerve signals that tell your muscles to contract, it can help smooth out these types of wrinkles.
