At first I was a little skeptical with this serum. When it first arrived it was a little more milky than the picture suggested, which almost put me off of using it.However, I’m glad that I decided to try it!This serum was very easy to apply, and I felt the hydration almost immediately. A lot of Hyaluronic acid serums have a characteristic “tingle” that those like me with sensitive skin might feel.I will say that the tingle was present, but was not bothersome. It goes away in a few seconds, and you might not experience the tingle at all if you don’t have sensitive skin.After a few minutes on the skin, I immediately noticed plumpness and hydration. This hydration lasted me from 8am to 8pm, which is a full day’s work for a skincare item.All in all, I would definitely recommend.
