For many years, I've sat at the right side of the car. Now that I look, I can clearly see that the right side of my face sags more than my left. My right eye droops more and the white underneath my pupil shows. Also, when I smile, the right cheek is bigger... My dermatologist said this was possibly caused by the collagen loss from the sun damage. Is there anything I can do to make my face symmetrical? Are there any treatments that don't require surgury?
