Crow's feet are small lines and wrinkles that appear at the corners of your eyes. They are a common skin concern and can begin to appear on your skin as early as your mid-20s. However, you may notice that they become more visible as you age, and that's because the skin around your eyes is structurally thin and more prone to becoming dry. As a result, it can lead to the wrinkles around your eyes appearing more prominent. If you want to reduce the appearance of crow's feet, use an eye cream formulated for your skin type and be consistent with it.
