I splurged and bought this serum and I truly love it. Most people complain becuase they are using too much of the product. 1/2 pump is ALL you need. I rub in an upwards circular motion until it has soaked in my skin. After I always apply a moisturizer and my skin feels so plump and hydrated. It has an odd spice smell to it, but that goes away as soon as it has soaked in. After a couple weeks of use I can see an overall improvement in my complexion. I have given 4 stars because of the price and the smell.
