How often should I change my mascara, considering the myriad factors that can influence its longevity and effectiveness? Is there a specific period after which the product may become less effective in enhancing my lashes, or should I base the decision on the physical condition of the mascara itself? For instance, does a change in texture or an unpleasant odor signal that it’s time for a replacement? Additionally, what are the potential risks associated with using expired mascara? Could it lead to eyestrain or infections, particularly if the formula has begun to break down or if bacteria has proliferated? Are there particular signs to look for that might indicate my mascara has overstayed its welcome in my beauty routine? How can I balance my desire for an effective cosmetic application with the health considerations that come into play with prolonged use? These questions swirl in my mind as I navigate the world of beauty products.
