As mentioned the black and white pictures clearly show the change in the face shape and brighter eyes.
The smile is becoming more attractive and Lydia looks altogether more radiant.. Is this because the corners of the mouth are lifting up more, the face shape changing and the eyes looking brighter? The improvement in the head posture also plays a part in how we perceive the smile.
The improvement in head posture is easier to see in these side profile pictures. Also the jawline looks sharper.
After just 10 minutes the smile looks more symmetrical and slightly lifted.
As you can see in the black and white pictures, the mouth appears more relaxed and the lines under the eyes have improved. Even after 10 minutes the face is starting to change and the cheeks are lifting.
The lines under the eyes are not as deep and not as long. The eyes are also slightly more open.
