Query: It just works

I tried this as part of a massage and I use it in conjunction with a few drops of Musclease, also from Elemis. I apply a small amount for back and shoulder tension daily between my shoulder blades and along the spine. When I use it, my tension is gone the next day. If I forget, I notice that the tightness is back. It's like some kind of expesive, magical balm! I'll buy it again, for sure.
