My favorite mascara. Lash Slick is "film-forming", which is Glossier's term for a "tubing" mascara. It wears far better than any of the oodles of tubing mascaras I've used over the years, which is quite impressive. Glossier Lash Slick does a beautiful job of separating lashes, and adding length. It never, never, never clumps or looks furry. Lash Slick also comes off with water or cleanser/makeup remover, and does not budge unless you want it to. I have never found a mascara that curls lashes and keep them curled like Glossier. I very rarely attempt to curl my eyelashes with a curler, because mascaras just take the curl away with their weight. Glossier mascara curls my lashes as I apply it, and it keeps them lifted up until I remove it! I haven't used a lash curler in so long I doubt I'll ever need one again. When Lash Slick sets, it does not budge. The curls defy my hooded eyelids, and the mascara looks clean, and fresh, and natural. To me this is an exceptional formulation. I can actually see my own lashes out of the corners of my eyes!
