Crow’s feet are the fine lines and wrinkles that form around the outer corners of the eyes – a characteristic sign of skin aging. In our younger years, these fine wrinkles only show when we smile or squint. Over time, the fan-shaped lines deepen and become permanently present from around the age of 40 onwards. Today, we can effectively treat crow’s feet with minimally invasive methods. Botulinum toxin, a muscle relaxant proven in wrinkle treatment, is the treatment of choice here.
