This is a very good mascara. It really lengthens your lashes although using a base mascara (ex. underwear for lashes from origins) is much more effective in lengthening. But it can be a hassle in the busy morning putting two separate mascaras. Definicil works well without the hassle of putting two mascaras in the morning and its lengthening effect is pretty good. it can clump a bit and may leave a little dark spot under your eyes at the end of the day but all in all, I'd recommend this mascara.
