1. Always replace your mascara every 3 months. This is the most hygienic replenishment time for all eye makeup products. Plus, it ensures your mascara never gets too dry and clumpy.
2. Always let mascara set (but not dry!) between applications. Two coats of mascara should always be applied, but never more than that. Wait 10 seconds for formula to set before applying second coat so lashes won't clump.
