I currently use the Bourjois Volume Glamour Care in the white tube - great in terms of being non-irritating, and the length of the wand compared to the brush is so nice to use, but it's not waterproof in any way and does flake off/smudge. How does the No7 sensitive Extreme Length one bear up? My lashes are quite thick but short and straight, so wondering if ones intended for Asian lashes might be good? I'd like it to hold a curl too.
