Don't get me wrong, the Rimmel 9 in 1 BB Cream does do its job. The problems I have with it are 1) the shades are very general, so initially it's very difficult to tell which shade you are. Since I have a tan/olive complexion, it makes colour-matching difficult, especially when the shades are that general. I have the medium/dark BB cream, which is not too bad, though maybe a bit dark for me. The main problem is the red pigment in the BB cream sometimes separates from the rest of the tones, leaving a slight red smear, almost like I've applied a light blush to my skin, which is annoying to fix. The product is also a bit too thick or maybe just a bit sticky, making blending it in a little hard, especially when using other products with it.
All in all, it does work to a basic extent, but is not an ideal BB cream.
I really like this bb cream. It has a nice consistency and goes on evenly. Its a good product to use just on its own when your just going for a casual look with minimal effort. I would use this again. It is affordable and readily available in many shops. I have quite dry skin and this product keeps it moisturized and smooth all day. It gives a moderate amount of cover on its own however I also sometimes use it as a primer before my foundation which helps to create a more flawless finish
