I only use this mascara on my bottom lashes, it is good, but there is always a tiny smudging after around 1 hour of wear, then nothing during the day - maybe it happens because of my eye cream I use in the morning. I never experienced this with Clinique's bottom lash mascara when using the same eye products, so I will stick to that in the future. 

Perfect for under eye lashes and works great on the top lash too.

The wand is super skinny as shown and it really is waterproof!

Really slim. Looks pretty natural and doesn't lower the lash curl. 

Help my eyelashes make them look longer!
