This blend is made with rosehip, avocado, grapeseed, French plum seed, and Squalane oils. According to the feel website, "clinical studies show a 5% concentration of Squalane oil gives a 51% reduction of wrinkles over 28 days." Those are some pretty major results! I can't speak to wrinkle reduction just yet, but so far I am really enjoying this oil. It is very thick so a little goes a long way, and they recommend using this only once a day (am or pm will work).
