The claims that come with this silicone- and talc-based primer sound amazing, but, in essence, this is simply an average primer that isn't nearly as revolutionary as Sunday Riley makes it out to be!
What supposedly makes this product unique is that it contains something called "Rejuvenox," which purportedly keeps the primer "drenched in oxygen." The ingredient that likely makes up Rejuvenox is perfluorodecalin, which can dissolve and deliver oxygen to the skin. Sunday Riley says this ingredient reduces wrinkles, moisturizes skin, and even has an anti-acne benefit.
There is limited research showing that, in certain formulas, perfluorodecalin has the potential to reduce fine lines and improve the skin's barrier function (Source: International Journal of Cosmetic Science, June 2006, pages 135–150). On the flip side, however, when oxygen interacts with the skin, it almost always loses one of its electrons, turning it into a damaging free radical. Although this formula isn't likely to cause excessive free-radical damage, it also isn't likely to provide any measurable benefit.
Science talk aside, this fluid product comes in a pump-style container and looks quite opaque when it first comes out, but once blended it's very sheer. It comes in three shades—Light, Medium, and Deep—and all are sheer enough to work on their intended skin tones. On bare skin the effect is a subtle evening out of the complexion. It also feels lightweight and moisturizing, and serves as a good base for makeup (makeup adheres well to it), but in our case, it didn't significantly improve makeup wear time.
When all is said and done, this is an average primer, with only a small amount of beneficial ingredients. It's not bad, but why pay this much when there are other primers that cost the same or less and that are packed with skin-care goodies like antioxidants and skin-identical ingredients that all skin types need? You can find them on our list of Best Foundation Primers.
