Bacteria breeds as efficiently in cosmetics as anywhere else, but convincing consumers of the limited shelf-life of their make-up has always been a challenge. Now there’s Timestrip®, which when added to packaging, provide a clear visual indication of when an item should be discarded and replaced.
Using Timestrip® will encourage consumers to comply with replacement guidelines. The Period After Opening (PaO) symbol already tells consumers how long a product will last once it is open, but Timestrip® provides the crucial bit of information: when it was first opened. Adding Timestrips® to packaging or integrating them into the packaging itself offers consumers an easy to use, easy to read and accurate indication of how old their cosmetics actually are.
Lipsticks and glosses– repeated exposure to bacteria from the mouth and temperature fluctuations experienced during life in a handbag mean these products should be replaced regularly.
Mascara and eye pencils– with a shorter recommended shelf-life than other cosmetics, out-of-date products can produce infections.
Foundation– the liquid variety especially, as it has a shorter recommended PaO.
Natural or organic cosmetics– fewer preservatives or none at all means a shorter shelf-life than conventional products and potentially higher levels of bacteria.
Temperature-sensitive products– Timestrips accelerate at higher temperatures, indicating if a product’s shelf life has been affected by warmer conditions.
