Smells fresh, absorbed quickly
Most skin treatment serums that  use often feel like they just it on top of my skin and are not absorbed.  This is a very lightweight serum, that smells fresh and is absorbed quickly.  I haven't used it long enough to say I see results, but I will continue using it- that's why I only gave it 4 stars.  Instructions say one squirt is enough because it goes far.  However, I use about 1 1/2 squirts and do my neck too.
Rating: 4 stars
