This 4.0 fl oz spray has lasted me three months, with use nearly every single day, and still has at least a month left in it. It's oil and paraben free and has temperature control. It prevents melting, cracking, and fading, for up to sixteen hours. There have been nights where I wear this out and don't take my makeup off at night (I know, shame on me!!!) and I wake up with my full face still perfectly in place. It sprays evenly and feels cool and refreshing. It dries quickly too. It's a $30 well spent and I would recommend this product to anyone who wants assurance that their makeup is going no where all night long!
