There once was a beauty blogger who loved her beauty products - she didn't tend to be someone who had just one product of each type on the go at once. The problem is, she would excitedly open all these products to try them as soon as she had them in her hands, without waiting and using up another of the same first. This meant that some unfinished products would get neglected for awhile and then sometimes forgotten. Other products, particularly those that were expensive, would be used too infrequently for fear of using up the product. A time would come where she'd inadvertently come across these products again, or think "Ooh I'd really like to use that XYZ today". But to her despair, some of them didn't smell, look or feel right on her skin anymore and she reluctantly re-homed them in the bin.
For example, her Eyeko Skinny Black Eyeliner, only used a handful of times, had dried out. She couldn't use the last few applications of her Elemental Herbology Cell Food Serum as it smelt a little off. The worst? She couldn't finish her beloved Antipodes Aura Manuka Face Mask - it started to tingle on her skin and she realised she was using it way past its 6 month useful life.
The moral of the story? Use it or lose it. Having too many beauty items on the go at once may result in wasted product, which equals wasted money. Plus what's the point of buying something expensive then not using it? This is an even bigger waste of money. Sensible solutions to help stop this happening so much in the future include a) writing the date of when new products are opened on the packaging and b) trying to be sensible with on how many products are on rotation at any one time.
