Regardless of whether you like your treatments novelty or all-natural, "face mask" is currently the most-googled beauty trend, meaning if you haven't got at least one in your bathroom cabinet you aren't up with the play.
New-gen face masks are capable of immediately noticeable results, making them as good for pre-event pick-me-ups as they are for those days when you wake up tired and your skin, frankly, looks knackered.
A mask like Ren's Flash Rinse 1 Minute Facial $63 (from Mecca Cosmetica, left), which uses vitamin C to improve texture and tone, can work its magic in the time it takes to brush your teeth.
If my skin looks particularly parched, I'll use Dermalogica's Skin Hydrating Masque $75 (middle) under my foundation as a moisturiser.
