I'm starting to wonder if MAC ever let their developers go home - it seems like they announce new products every day!
The latest product is an update to their Opulash mascara; Opulash Optimum Black. An extra volumising version, the brush apparently delivers even more curl and density.
MAC also say it resists flaking, smudging and humidity (not that there's much chance of us encountering humidity), has a conditioning formula for healthier lashes AND it supposedly lasts 15 hours too. Excellent. Hopefully we'll have a review for you soon!
