This is an extremely lightweight serum that immediately sinks into the skin. My skin feels instantly hydrated and has a wonderful glow (my favourite). The biggest difference I noticed was the appearance of my pores. Large pores is one of my biggest skin concerns and this serum instantly makes them appear smaller/blurs their appearance. My skin also feels a lot smoother and softer to the touch. It does leave the skin a little sticky, however, not enough to be annoying and it could be great for makeup.
