This may sound like overkill, but it really works. Where some mascara products are specifically designed to lengthen lashes and others are more effective at adding volume, multi-purpose mascara does both. Most budget brand mascaras fall into the multi-purpose category. This one-size-fits-all approach sounds efficient, but it may not do as good a job as using a volumizing mascara first and then following up with a lengthener. This means investing in two types of mascara, but the results can be impressive. Let's face it, mascara can look gloopy and overdone if the formula is off. Experiment with different products alone and in combination. It's the best way to find the right look for you.
