In her Rimmel London thrill seeker mascara review, she detailed: “It doesn’t go on clumpy, instead, each lash looks individually lengthened for a fanned-out effect.” “I don’t have naturally long lashes, but Rimmel’s mascara delivers impact with minimal effort,” she wrote. “Though the brand claims it offers up to five times more volume, I’d argue the formula is more lengthening and curling than volumising, working to elongate the eye.”Buy nowMaybelline instant anti age eraser eye concealerIndyBest beauty writer Lucy also loves the Maybelline concealer (Lucy Smith/The Independent)If you’re after a concealer for mature skin, this one was our top budget formula.
