PS... 3 Step Mask, €2.50, Penneys

The main event is a sheet mask infused with hydration-boosting hyaluronic acid, but there’s also a dose of a pre-mask serum, and an after-mask moisturiser. “This is a great pick-me-up to pop in an overnight bag for a holiday night away,” said one panellist. “It’s three boosts in one pouch.”
