We are pleased with the body armor, shampoo, hand wash, and squaline oil. We use these for everything imaginable. I highly recommend these. The tone seems to be specific in its use for hands that need intensive treatment for cracks in the skin. I'm sure it works, but it does not fit into our skin regimen.
Has worked great for both my wife and me for about 4 years. We believe it keeps colds and related sicknesses to a minimum and not bad. We spray twice daily. Pricey but worth it.
