For now, the foundation bars are limited edition (cue the stampede) and available to buy online for a month from Friday 29th June, but we're pretty certain they'll become firm fixtures in the range, and according to Rowena, there's scope to make new formulas. "There are so many natural ingredients that are great for treating acne-prone skin, for example, so it would be great to expand," she adds.
