I've just started using it, so I'm not sure yet. I've been using Majo Majo's eyelash serum for about a year now. It was great that it gave me firmer, more volume, but it was hard to apply to my lower lashes and the outer corners of my eyes, so they didn't grow, so I switched to this. Unlike Majo Majo, it stings a bit when it gets in my eyes, but I'm looking forward to it.
