I started using this CellexC serum 25 years ago after having a facial at a local highly regarded spa. My skin was slightly oily, but very sensitive. My skin at 65 it is now much drier, but still finicky. I have tried many Vitamin C serums over the years, usually trying to find something less expensive or that has more hype, but I always cones back to this one. The ingredients are simple and it has zinc to calm my skin, AND it works. I’ve played tennis and golf over the years and had a lot of sun exposure, albeit with sunscreen, and my skin looks 10-20 years younger than most of my peers. If you are looking for a simple, non-irritating , and effective serum, look no further.
