If you prefer a traditional waterproof formula during the summer months, Barnes suggests the new Max Factor Divine Lashes Waterproof Mascara (£12), which features a silky, whipped formula that not only won't clump on your lashes, but more importantly won't become flaky and crumbly halfway through the day. We also appreciate it doesn't take brute strength to remove it — just a little makeup remover and reusable cotton pad.
