Five stars for the serum, 3 stars for the pump = average 4 stars.The serum is lovely, light, no fragrance, and seems to brighten and moisturize. However, the pump delivers enough to cover my entire face! I've tried to depress the pump only part of the way, but so far it seems to deliver all or nothing, so I often unscrew the top and drop serum onto my fingertips. I haven't noted any other reviews that mention the pump, only a person who says she uses it on her entire face. The pump isn't a deal breaker, and I do appreciate that the glass bottle allows me to see how much product remains.
