I have been using this serum for several weeks now and I really enjoy it! It starts off a little sticky but dries down completely to a “nothing” feel. There are no harsh scents, and it leaves my skin feeling right – not oily or dry, just hydrated like normal. It goes well under many different moisturizers for day or night use! I haven’t noticed any drastic improvements from using it, hence the 4 stars. I wouldn’t say that my pores are smaller or that my wrinkles have shrunk lol, but I truly have no complaints! I will continue to keep on using it!
