Can you remember how old your mascara is, or when the last you bought a new fragrance? Those that prefer their products to be natural and organic may find that the formulas expire even quicker. "Emulsion products like creams (also cream foundations), lotions and moisturisers are likely to expire more quickly than oil, alcohol or wax-based products," explains chemist and product formulator Ric Williams. "Cheaper products may expire more quickly too, if for example they're poorly formulated without stabilisers, or have not been checked for stability." Bacteria build-up, over exposure to oxygen and heat can make your make-up and skincare go off.
