The Iconic London Seamless Concealer (£22) is quite similar to the Laura Mercier Flawless Fusion formula — hydrating and full coverage, but with a slightly thinner texture. Both POPSUGAR Content Director Sophia Panych and London-based makeup artist Neil Young are fans. "It has a nice creamy texture and sets without looking too heavy," Young said, while Panych likes to use it not only for her under eyes but also on her forehead and chin and around the sides of her nose in place of foundation. "It covers up anything, be it dark shadows or redness," she said.
