I have read that strontium can be used to firm the skin. Can any strontium be used and what would be the percent to water etc thanks. I have bought strontium "citrate" I believe for my osteoporosis and wondered if I could just open the capsule of this and mix with water to spray on?

I haven't seen any research indicating that strontium firms the skin. If you have and references to research papers, please post, I'll take a look.

Here is a google patent for the invention to use strontium to help firm the face:

google.com/patents/US20080026074?dq=strontium+sivak&hl=en&sa=X&ved=0ahUKEwiCxtO6tITTAhVK5mMKHULqCCMQ6AEIGjAA

This patent was filed by Hannah Naomi Sivak (She runs the DIY website SKINACTIVES) and Mary Hunter.

Skinactives sells their product to firm the face with strontium in it called "Anti-Aging HydraMist".


What do you think about this, Dr. Todorov?

"The present invention provides methods of improving the appearance of sun damaged skin and/or aged skin. More particularly, the invention provides methods of treating skin using compositions that include strontium divalent ions.
[0010]
The entry of calcium into cells via voltage dependent channels regulates muscle contraction and neuronal discharge.
[0011]
Some divalent inorganic ions, such as barium and strontium, mimic the ability of calcium to pass through the voltage dependent calcium channels. Strontium (Sr) is located below Calcium in the Periodic Table of the Elements. Sr++ is a divalent cation that may also compete with Ca++ for binding to some receptors. This capacity of strontium ions maybe responsible for the analgesic effect of strontium, an effect taken advantage of in dentifrices, alleviation of skin sensory irritation and, taken orally, for arthritic pain. Calcium is thought to play a role in the pain process by regulating the release of the chemicals that nerve cells use to communicate, and strontium would compete with calcium, effectively hindering entrance of calcium into the nerve cell.
[0012]
Strontium is taken orally to help with osteoporosis. This particular use has led to extensive toxicity studies and it has been found that even for long term use, toxicity is not a problem.
[0013]
We have found that application of strontium ion in a suitable carrier, e.g. a distillate of orange flower petals (neroli floral water), within minutes of application changes the texture of photoaged skin, resulting in a more youthful complexion. The epidermal ridges are less pronounced, an effect that may be related to relaxation of erector muscles."



The patent tells us how much strontium to use in the formula:

"Application of a lotion containing 6 grams of strontium ion per 100 mL, using as diluent distillate of orange petals and distilled water in equal volume, smoothed out the skin and increased skin turgidity within a few minutes. This effect lasted for about 4 hours.
[0015]
This smoothing effect could be observed even when the strontium solution was applied over a layer of powder make-up."

A patent is not a clinical study. Besides, they only claim a transient cosmetic effect rather than any lasting improvement.

Too bad there aren't any studies on it, just a theory by the person who filed the patent on how it might work in the skin, but it is not proven why it tightens the skin.

Thanks, Dr. Todorov.
