For reference, I am 35 with fair, sensitive skin. With that in mind, I found this to be a great serum! The consistency is more moisturizing than other serums I've used. It also has an almost gel-like quality to the serum that aids in absorption. I have two other brands in rotation, but I find myself reaching for this one time and time again! I will definitely purchase when my others run out. As for results? I'm not sure if it's my overall regimen that has produced fabulous results, but my skin is looking more even and my crows feet diminished.
