This a biphasic eye make-up remover, with a blue tinted organic layer floating on top of a colourless aqueous layer. Helpful when mixing & shaking before use, an overall lighter blue cloudy appearance means you're good to go. I use it with plain old round baby cotton pads, squirt a bit of this onto each pad then hold over my eyes for ~2-3 minutes to soften mascara on them, then gently start rubbing mascara off lashes using the pads. It comes off easily, too. If this gets into your eyes accidentally, it doesn't sting (so long as it's not dripping down and taking liquid liner with it).
This easily removes my usual daily mascara - Heroine Make Long & Curl waterproof mascara, or should I say bulletproof? Either way, it's notorious for being difficult to remove, but this takes care of that. It also easily removes lip stains, tints, and NYX's lip lingerie liquid lipsticks. I've been buying this for years, no need for pricey make-up remover when this does the job just fine.
