The results show that the thickness of the upper and lower lips in the process of aging is significantly reduced. In addition, the width of the lips and the fullness of the lower lip, shown in the photo in profile was also changing for the worse. The study also showed that the area above the upper lip under the nose increases with age. A more detailed study by age group showed that these changes begin around the age of 40 years. According to experts Cao, this phenomenon is associated with changes of internal tissues, and reduce muscle tone.

In the second part of the study, Cao was attended by 13 Japanese women aged 46-55 years. At this stage, the scientists first measured, and then compared the various parts of the lips participants of the research on portrait photographs taken in 1992, 2002 and 2015.
