I purchased two eyeliners (L'Oreal and Revlon) because I knew that there was a product for me that lasts more than an hour. I like a bold black eyeliner. Whenever, I placed previous eyeliners on, it would just fade away. Yesterday, I was going to experiment and place L'Oreal on the left eye and Revlon on the right. L'Oreal was noticeable right away as a bold color. Guess what? As time passed away, the bold color didn't move. Say what? This morning, it is still there!!! I've never seen this before. I am going to start to wear their makeup and see if their foundation lasts as well. Thanks L'Oreal!!! Finally!!!
