Customer Reviews

Rated 5 out of 5 by from A worthy investment I had to do a lot of research before I could justify paying £83 for a serum. But just like the reviewers I saw for this product, I'm amazed. I've never thought I needed to use a serum before and always trusted my moisturiser. I've realised thay I've been neglecting my skin for years after seeing the difference this serum has made. After around 3 weeks of using the serum(a third of a bottle) I can see that where there were crows feet starting to form, my eye area now looks firmer and smoother. I can imagine this is going to be a regular buy from now on.

Rated 5 out of 5 by from Amazing product I always research my products and their ingredients before purchasing and with this product I was expecting great things. It did not disappoint! My skin clarity has dramatically improved and I love how hydrated and smooth my skin feels.

Rated 5 out of 5 by from great product I've been using this since Skinceuticals got it out on the market. My aesthetician recommended it and it was love from first sight for me. I have a very sensitive skin and unlike some of the other serums from the same line, I never had any reaction to the H.A. Intensifier. I would say that I saw results shortly after I started using it. In combination with other Skinceutical products (I use the Vit C serum and the Metacell moisturizer), it feels absolutely fantastic.

Rated 2 out of 5 by from Higher expectations than delivery I bought this serum a number of weeks ago and had very high expectations considering the price. All in all I have seen only a small improvement and in fact saw a much better result from using a similar serum from another brand which was only a fifth of the price.

Rated 5 out of 5 by from A must try I decided to get HA intense to try out and I love it. It is the best correct serum that I have use from skinceutical. I used to use B5 gel but it wasnt enough hydrated for me. HA intense seems to be better for my skin, my skin is very smooth and hydrated! (This review was collected as part of a promotion.)

Rated 5 out of 5 by from Best serum I’ve ever tried I’ve never bought a product and be impressed with the results. Normally I am underwhelmed but this serum just makes my skin look much more even toned and plumper it’s hard to describe but I’ve found it revolutionary. (Age 41 and have oily skin)
