Our skin, lips, eyes, lashes are full of everyday bacteria. If we knew what the bacteria on a mascara wand looked like after a week we would probably run screaming. It is important to do whatever we can to reduce the health risks we’re exposed to either way. First step is to throw away makeup products at certain intervals, depending on their composition and, naturally, frequency of use. While there are no well-defined rules for when to throw a cosmetic product away, cream and liquid products should be replaced once every six to twelve months, while powder-based ones once every one or two years.
Mascara is, however, the exception in all this, in that it must be replaced for a new one more frequently. Buy a new tube of mascara every three months, for two very practical reasons. First off, after this time interval, it’s most likely dried out, that is, useless; secondly, the eye area is more prone to infection than the rest of our face so we should see that we don’t expose it when we can best avoid it.
