For the study, his team looked at medical records of 20 black adults from 1973 and 2017. The study patients had at least two face scans taken 10 years apart.

Although all of the faces changed over time, they showed only minor changes, compared to similar studies on the aging white population.
"This finding reflects other studies that show black adults have higher bone mineral density, decreased rates of bone loss and lower rates of osteoporosis as compared to the general population," Paskhover said in a university news release.
Facial aging results from a combination of changes to the skin, muscle, fat and bones.
As people age, the loss of mineral density causes bone loss. Bone loss can affect the shape of the nose, lower jowl area, cheekbones, and middle and lower areas of the eye sockets, the researchers explained.
"As bones change, they affect the soft tissue around them, resulting in perceived decreases in facial volume," Paskhover said. "Treatment should consider the underlying bone structure."
The report was
ed online recently in JAMA Facial Plastic Surgery.
