I like its plumping effect on my face. I use it on wet face then immediately seal with a moisturizer. It instantly hydrates the skin when used properly. Though I don't prefer a separate hyaluronic acid product because it's usually already in moisturizers and sunscreens, I didn't experience unfavorable effects so it's definitely worth a try. A good addition in a routine for those who enjoy layering hydrating products on the face.
