Review title is Great hydrating serum! [SEP] I love using Hyaluronic Acid on my skin, so I was very happy to be able to this serum for my honest review. I have noticed that as I get older (I am now in my late 40s), my face looks old and dry. I have many more fine lines and wrinkles also, especially around my eyes. I have very sensitive skin and break out easily, so I have be careful what products I use. I had no breakouts or irritation with this serum. I really like the consistency of this serum. It's not too thick or too thin and it's nice that it has a pump instead of an eye dropper. I find that easier to use. One pump was more than enough to cover my entire face. I love how hydrated and youthful my face looks after using this for 2 weeks. It also makes my face feel so smooth. I did not put a moisturizer on after the serum, because I wanted to see how my skin reacted to the serum alone. As I said, my skin looked so hydrated and felt so smooth, that I didn't want to put anything on top of the serum, so I know that this is really working.
