"Nars Powermatte Lip Pigment in Wild Night (£23) is a gorgeous deep purple that can look brighter or deeper depending on your underlying natural lip tone," said makeup artist Martin, the man responsible for Meghan Markle's ultrapretty wedding-day makeup. "It's great as a stain underneath your face mask. A tip to help mask transfer from your lipsticks (especially liquid lipsticks): blot with blotting papers before you put your mask on."
