There are many definitions of “sustainable” when it comes to beauty products, with a whopping 66 eco-labels around the world relevant to cosmetics and personal care. One label that piques the interest of those of us at Water Footprint Calculator is the “waterless beauty” label. This South Korean term generally refers to products containing no water. Concentrated formulas can help reduce water waste but – and this is important to note – “even if a product arrives with no ‘aqua’ listed in the ingredients, it’s highly unlikely that it has no water footprint.” This is because it can take a lot of virtual water to grow and harvest ingredients, and to pack and ship products.
