Rimmel London Lycra Lash Extender is my most recent mascara purchase. I wanted something which would make my lashes thick, long and that would also last right throughout the day. I have used many mascaras, this one is one of my favorites, perhaps not my all time favorite, but still very good value for money. Indeed it does thicken and elongate my lashes and it pretty much does stay on all day. Sometimes mascaras are so thick you feel like your eyelids are carrying a comb - this is not it. It makes you eyelashes long, but natural. I don't like mascaras which flake and disintegrate a bit towards the end of the day - again, this is not it. It really does stay on until you wash it off. But if I have to be really picky, there has been the odd occasion where I may have sneezed, my eyes have watered and the addition of this mascara seems to irritate my eye temporarily. The package indicates that you can expect 60% more length and this I would agree with. However it also states that you can expect 50% more curve and this I'm struggling to agree with. However all things said, I'm quite pleased with my purchase and would purchase it again. My eyes have become somewhat more sensitive over the years so just maybe the irritation problem as at my end!
