From a cosmetic point of view, almost everybody exclusively focuses on the skin to counter aging, when they should be at least as concerned with bone density.

From a cosmetic point of view, almost everybody exclusively focuses on the skin to counter aging, when they should be at least as concerned with bone density. Lots of people have perfect skin, but they still look old. Why? Bone morphology. The zygomatic bone erodes, and the orbital gaps widen. The mandible degrades and pivots down and backwards (jaw rotation). Issues like resorption are currently very challenging. Skin is comparatively much easier. Also (and besides well-known interventions like collagen, retinoids, HA, and dermarolling), Epidermal and Keratinocyte Growth Factors are already very cheap, and showing much promise.

This interested me, but I had to look up some of it: Zygomatic bone: cheeck bone, https://en.wikipedia.org/wiki/Zygomatic_bone https://en.wikipedia.org/wiki/Zygomatic_bone Orbital gaps: hollow areas around the eyes Mandible: lower jaw, https://en.wikipedia.org/wiki/Mandible https://en.wikipedia.org/wiki/Mandible Resorption: a process in which a substance is lost by being destroyed and then absorbed by the body. HA: hyaluronic acid

  For anyone else wondering: your body is continually pulling calcium from your bones for metabolic processes. Usually it gets replaced when you consume something with calcium in it. It makes sense to have somewhere to store extra nutrients so you can keep functioning for a long time between taking in those specific nutrients again. Your body does this with a lot of your organs. Fat is obviously calorie storage, but muscles can also be resorbed for energy under starvation conditions (or just when they're under used). Your kidneys can resorb water from stored urine, and your intestines pull most water out of what you consume. Most neurotransmitters and hormones get recycled at various rates and turned into new molecules. I'm sure there's more, but that's all I know of offhand.

And what be done about bone density? I guess exercise would help but not with the bones in the head?

  From [1]: > Animal and human studies suggest that high-frequency, low-magnitude vibration therapy improves bone strength by increasing bone formation and decreasing bone resorption. So you could apply vibration to the head bones. Not sure about any side effects. [1] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4458848/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4458848/

    Before you apply vibrations to your skull, note that it contains other things than bones that might be less thrilled about said vibrations. Or more thrilled, who knows - be careful out there, and if you do something stupid, take notes and share the results for our entertainment^W learning!

      Well, I apply a vibrating device to my skull every morning and evening (indirectly). It's my electric toothbrush :)

      Indeed. Wasn't there an article just a few days ago about Navy Seals (?) suffering brain injury from being too close to artillery being fired or some such? The vibrations in the skull were thought to be the culprit.

        That was shockwaves that damages brain tissue as it passes through it. Dont try to use a jackhammer as bone vibrator.
