ialuronic acid

I've written about this on here in the past. Ialuset cream.
My Dr. in France prescribed it to help heal a small leg wound, and it worked very well.
Husband had an injection in his knee based on the same thing with excellent result. He would never have managed all the work involved in our move back without it, (he could hardly walk, )and his knee is still ok, TG. Helps rebuild cartilage.
But I've never tried it on my face. It's evidently the main ingredient in expensive facial serums.
