If you look in the mirror and see new wrinkles forming, you likely blame aging skin. But emerging wrinkles may actually be signalling diminishing bone density. It turns out osteoporosis and skin crepiness share some surprising connections.

Several studies reveal that women with osteoporosis and osteopenia tend to have more pronounced wrinkling and other signs of skin aging compared to their peers with normal bone density. Why does low bone mass translate to wrinkly skin? A few reasons explain this link:

  • Collagen loss – the collagen matrix that keeps skin plump and smooth is the same collagen that maintains the skin plump and prevents wrinkling.
  • Hormone changes – oestrogen decline during menopause can accelerates bone loss and decreases collagen and skin thickness. This contributes to sagging and wrinkling.

Studies show that skin and bones share common building blocks-proteins, and aging is accompanied by changes in skin and deterioration of bone quantity and quality. Deepening and worsening skin wrinkles are related to lower bone density – the worse the wrinkles, the lesser the bone density, and this relationship is independent of age or of factors known to influence bone mass.

Your wrinkles are trying to tell you to take care of your bones! Don’t dismiss these visible clues your body provides. Boosting bone density through having collagen daily, including weight-bearing exercise, nutrition, and other interventions can renew skin thickness and hydration.

… a prospective, population-based, 2-year observational study of Canadian adolescents aged 16–19 years showed that those who used combined hormonal contraceptives (CHC) had decreased gains in femoral bone mineral density compared with those who did not use CHC. Loss of bone mineral density on CHC was unrelated to dose of ethinyl estradiol. Earlier data had already shown the lack of a dose effect from CHC estrogen on bone; patients on 20–35 ÎĽg ethinyl estradiol CHC formulations all had suppressed markers of bone remodelling. Our recent meta-analysis comparing adolescents who did and did not use CHC also showed impaired accrual of bone mineral density among CHC users across a wide range of doses.

Why might adolescents taking CHC have lower gains toward peak bone mineral density than those not taking CHC? Bone resorption and formation are tightly coupled physiologic processes. As with the lower doses of estrogen in menopausal hormone therapy, CHC suppress bone resorption and therefore prevent the necessary bone growth that adolescents require to reach peak bone mineral density.
