I've spoken before about my love-hate relationship with hot weather in the UK, and the prospect of London hitting the heady heights of 37°C later this week has me feeling less than joyful. In fact, I'm seriously dreading it. Sure, if I could spend my afternoon unwinding in a beer garden, the impending heatwave might be a little more alluring, but I'm guessing most of us don't have that luxury. Instead, I've already stocked my tote bag with a few key beauty products I rely on every single time the temperature soars. Some of them you might already have in your beauty stash, while others might be a little more unexpected, but trust me: They might just help you survive the heatwave this week.
