Lipgloss, like food, has an expiration date. Once opened and used, bacteria is introduced to the product. Consequently, the product should be replaced nine months after opening, according to Cargo Cosmetics.
To keep lipgloss fresh, Cargo introduced gloss packaging that incorporates Timestrip technology, a tiny strip embedded in the cap of the gloss to keep track of how long the lipgloss has been open.
According to the company, this “best-before” date has become so important that European Union countries recently launched legislation requiring cosmetics companies to have a Period After Opening (PAO) time frame listed on their products.
