This serum was nice but nothing too exciting. It did hydrate my skin but I didn’t feel anything remarkable. There are other more affordable serums that will have the same effect or better. I haven’t purchased again, but it was nice enough. 

If you don't have a problematic/acne prone skin this might be very good for you. For me however - unfortunately this serum causes acne. Like everything else but Sturm's Hyaluronic Serum.

I feel like it's one of the hyaluronic acid serums that actually does something. I'm extremely acne prone and this does not break me out. I had really dehydrated oily skin before this serum and now I'm a lot less oilier and a lot more hydrated. I've been using it for about a month now and I know I'm definitely going to repurchase. It sinks right in and one pump is also enough to do your whole face, neck, and even shoulders.

I discovered this product 3 months ago, I am now addicted to it - leaves your skin hydrated and absolutely flawless. A bit expensive though...

I've probably finished 5 of these already. I have oily skin and this serum feels like applying water to the face. It is also great to mix other serums into it (Pai blemish serum or Drunk Elephant TLC). It sinks right in and leaves your skin plump and hydrated. I love the high concentration of HA in this.
