Argan oil has been one of the most talked-about beauty ingredients of the last few years, and it looks like things aren't slowing down. We've got used to the wonder oil being used in our hair, on our faces and over our bodies, but how about on our eyelashes? Rimmel's new Wonder'Full Mascara (£6) adds the oil to a traditional mascara formula to help soften and condition the lashes whilst adding length and fullness. If you're a mascara junkie, this could be just the product you need to keep your lashes strong, flexible, and full without sacrificing the drama. The addition of oil gives the mascara a smooth feel, helping to minimise clumps, while the flexible brush helps to give an even application. While you may wish to return to your favourite designer mascara for night, switch to this during the day and your lashes will thank you!
