The new Laneige Hypoallergenic Cica Sleeping Mask ($34) is already rather popular with other Sephora shoppers, who've given it 4.8 stars (with 98 percent also saying they'd recommend it to a friend). The overnight mask is great for dry or sensitive faces, as there's fermented forest yeast extract —aka cica — to moisturise and strengthen skin while you're getting some shut-eye.
