Rimmel London Lash Accelerator SERUM review

The serum is clear and a somewhat gel-like feel as it dries on my lashes. The applicator for the lashes is horrible. There is not enough depth to cover the entire lash and separation is non existent.I first used it as an overnight treatment and when I woke up there was goo hanging off my lashes. Removal was easy, but a pain.
The brush on the end of the applicator can be used on lashes or brows. I never used it on my brows but I did use it to get to the back of my lashes. 
After weeks of usage, I saw slightly longer lashes, but once they reached a certain length the improvement stopped. I purchased the Lash Accelerator Mascara and tried using the serum as a primer but the two became a complete nightmare of goo and fibers in my eyes.
