I was gifted the Revlon ColourStay Liquid eyeliner by Beauty Bulletin (BB) and was VERY excited to try it out, as I had never tried a Revlon one before.
Initially I loved the packaging, I think its quite sleek, and fits easily into my makeup bag, and for that i was impressed. The felt tip applicator was great, firm, and made drawing on the eyeliner on the lid, easier and more manageable. However, I was not impressed with the colour.
With eyeliners you want the colour to be a jet black, blackest black, but this one looked more on the faded side, which meant I had to do several various strokes to get a black BLACK colour, which made it time consuming, and messed up the precision of the line.
Again I found it to smudge easily, which made it fairly difficult to use.
However, I think for a beginner to liquid eyeliner, it is worth a try, because it does the job, not not a GREAT job as some of the Loreal and Stila liners. Its quick drying, so it is worth a try if you are new to the liqud eyeliner game.
