Perfect for day to night. I wear this almost every day as I often go straight out socialising after a day in the office. Keeps me from looking tired as it doesn't wear off.

When applying it, be sure to be careful as if you accidentally get some on your skin it doesn't wipe off as easily as non-waterproof mascarra will. As a mascara it's pretty standard coverage - not clumpy or lumpy and gives an even coverage. I woudn't say it was particularly lengthening or thickening for my lashes - the main benefit of it is definately the length of time it will stay looking like you've just put it on.

Also great for at the gym as the sweat doesn't make it run! To remove I use a make up wipe and it comes off quite easily. Have also used a specific eye make up remover which works equally well
