I bought this to try as I was low on primer, generally like Rimmel products, and it was very cost friendly. I've been using it occasionally now just to use it up but I wasn't overly impressed with it. The texture reminded me like more of a lotion-like glue which I didn't really like the feel of and my skin didn't look any smoother once it was applied. I didn't notice my makeup lasting any better than when I don't apply primer, either.
However, it might not be the right match for my skin and could work well for other people so would be worth a try.
I love Rimmel products they are cheap and generally do the job. This was no exception. It acted as a great smoothing primer for my face. It made foundation glide on.
My only issue was that I have combination skin and found that it was a tad oily. I purchased the clear one, if that makes any difference and I definitely think it does a better job than no primer at all but it's not my first pick.
