Dr. Lubna and her coinvestigators gave 114 postmenopausal women a score for face and neck wrinkles (based on the number of sites and depth). They also attempted to measure skin rigidity, using a durometer. BMD was measured with DEXA.
They found a significant association between wrinkle severity and bone density; more severe wrinkling was associated with lower bone density.
It is not as far-fetched as it may sound. After all, skin and bone share some common building blocks - collagen. Changes in collagen with age may affect both skin and bone.
However, all bets are off for women who cannot refrain from botox, fillers, peels, and plastic surgery.
