The Farmacy Sleep Tight Firming Night Balm (£44) is spiked with echinacea, an ingredient that apparently does just as much good for your skin as it does for your immune system. Slather this rich balm on your face before heading to bed, and while you'll look a little shiny as you're sleeping, you'll wake up with skin that looks and feels smoother, plumper, and glowier. If you don't like the feeling of heavy creams on your skin, I'd say skip this one, but for everyone else, the Sleep Tight Balm transforms your skin overnight — and comes in super handy during the Winter when your skin starts to look a little dull and ragged.
