You can take some steps to prevent broken capillaries. Be gentle when you wash your face and use warm water. Apply sunscreen to your face, particularly around your nose and mouth, when going outside. Don’t abuse alcohol. While these measures won’t prevent broken capillaries in every case, they can help minimize the chance that you’ll develop them.
If you do develop telangiectasia rosacea, you can seek treatment from the Derma Clinic.
