Which part of the face is the crow's feet?

Fine lines known as "crow's feet" generally appear between the outer corner of the eye and the temple area. Specifically:

Crow's feet typically develop in the region between the eyes and temples. Because the skin around the eyes is relatively thin and delicate, combined with frequent facial expressions such as smiling and blinking, the periorbital muscles repeatedly contract and relax. Over time, this leads to aging and breaking of the skin's elastic fibers, resulting in fine wrinkles. These wrinkles are named "crow's feet" due to their resemblance to a fish's tail and are a noticeable sign of facial aging. Their appearance is not only related to aging but also influenced by multiple factors including individual skin type, lifestyle habits, and environmental conditions.

To reduce crow's feet, it is recommended to visit a reputable medical facility and receive treatment under the guidance of a qualified physician using injectable botulinum toxin type A. This treatment involves injecting botulinum toxin type A directly into the areas around the eyes to prevent muscle contractions, thereby smoothing both the muscles and the wrinkles. The typical reference price for injectable botulinum toxin type A ranges from 2,000 to 10,000 yuan per injection. Results are usually visible within 1–2 weeks after injection, although mild side effects such as slight burning sensation, redness, or swelling may occur.
