Fine lines under the eyes can be categorized into dynamic fine lines and static fine lines, which can be removed by injecting Botox, hyaluronic acid filler and facelift surgery, etc. The specific treatment is related to the patient’s condition. 1. Dynamic fine lines: Dynamic fine lines under the eyes are commonly caused by excessive facial activities such as repeated frowning, etc. Patients can inject Botox to relax the muscles to remove fine lines under the eyes. 2. Static fine lines: Static fine lines around the eyes can be caused by dry skin, collagen loss, etc. Patients can improve the appearance of fine lines by hyaluronic acid fillers, and if necessary, they can also take facelift surgery to remove fine lines. It is recommended that patients with visible fine lines around the eyes consult a regular hospital in time to assess their condition and choose the appropriate treatment under the guidance of a doctor.
