I am so very happy to have found secret sauce. I'm 56 and a few years ago really started noticing marionette lines in the jowl area and creases between the brows. This treatment really helps improve that. It is pricey but I was told to just use as a spot treatment in areas where needed in conjunction with my moisturizer. Not only am I findning this to be more effective, but it lasts much longer as well.
