Scientists have shown the full scale of the "microbeads" problem, with some face scrubs releasing up to 94,000 plastic beads into the environment each time we wash our faces.
The tiny beads are used in many products, but do not break down in water, and so end up in the sea where their size can make them appear like food to plankton and small fish.
The chemicals in the beads, as well as the beads themselves, can cause physical damage, which is then passed up the food chain to larger fish and birds.
More than 1.1 million people use a face scrub each day, and scientists at Plymouth University revealed that a single tube can contain a whopping 2.8 million microbeads.
There are plenty of microbead-free face scrubs on the market already. Cosmetics Europe, a representative body, has recommended that microbeads be phased out, with many companies planning to do so.
