Now that's covered lets move over to application! A Blending Sponge should be used damp! Say it louder for the people in the back! For multiple reasons, some of which you may not have been aware of – when the sponge is wet, it will absorb much less product, therefore you'll waste less! Having a damp surface will also ensure you have streak free, good even coverage and a dewy finish.
Golden rule - You must wash it. And regularly. You have to bear in mind, that while this is a great beauty tool, it is still essentially – a sponge. And sponges naturally will wear out over time. So to give your Blending Sponge the longest life span, you should gently wash it weekly with a mild cleanser or if you don't have that, baby shampoo will work just as well.
Last but not least; being a jack of all trades, we think it's just good practice to keep one on you throughout the day. If you're feeling in need of a bit of a refresh simply spritz on your finishing spray and dab this all over your face, making you fresh and dewy all over again!
