Ethical mink eyelashes don't exist, but even if the claims about brushing were true, the process certainly couldn't be considered cruelty free. Mks, like wild animals, do not need to be brushed. Have you heard of mink fur eyelash and brow extensions? They have been around for a few years and are used to provide longer, realistic-looking eyelashes and eyebrows. So yes, mink eyelashes are vegan and cruelty free, and have nothing to do with animal mink.
But mink eyelashes show off a much more sinister side than it seems. It is fueling the burgeoning mink fur industry, in which animals suffer enormous fear, stress, torture, disease and inhuman sacrifice when it is considered that they are no longer profitable. Eyelash extensions come in a wide range of animal-friendly fibers to fit every budget and every desired effect. Mink eyelashes are an all-natural product, meaning they have incredible shine and look a lot like real eyelashes once they've been curled to shape them.
