Bioderma Hydrabio Eau De Soin, £9
It’s 3pm and it’s not just your energy levels having a slump (pass the Kit Kat) – your face is looking a bit weary, too. This is the first water-based facial mist that hydrates parched skin, halts premature ageing and offers UV protection all in one spritz. Just whip it out whenever your skin feels dehydrated, for an instant hit of freshness.
