When I first started using this I was a bit uncertain, I've tried so many eyelash serums and none of them worked! But after only 2 weeks I was proven wrong. My lashes went from around 4mm (yes, my lashes are tiny) to around 6.2mm! And they look so much darker and healthier. I'm not sure if the day use eye cream is that useful, but it smells nice so I use it anyway. The only thing was the measuring card didn't fit my eye shape, so I had to cut a small part off so it can fit my eyes. I highly recommend this, and I can't wait until the 4th week! ^-^
