Sue here is an odd suggestion but it seems to work. THe ever lovely Diane had some issues with her skin, nothing major. A friend of ours is a vitamin D advocate and has this very cool toy.
It is a near infrared light machine. (Not its technical name, but I don't remember everything so well) Anyway in 3-4 treatments her skin was good as new in the affected area.
I have read ads about folks who offer the treatment and some sound like quackery (they read like the light fixes everything from pain to flat tires) BUT my friend offered the use of his machine not pushing the possible outcome. His machine is about $20,000.00 but he runs tanning salons. He kept it for himself because his dad had ciruclation issues that the machine helped.
If you can find the machine at a DOc or place by you it is a chnace that might give great results. I will talk to John and get the exact name of the machine and therapy when his is back from vacation.
