Green tea is more often found in a mug than in an exfoliating sponge but the caffeinated substance has anti-ageing properties and works wonders to encourage cell turnover. Maintaining the skin’s elasticity and tone, this works best for those who suffer from air pollution regularly, as it refines the skin’s texture and is full of antioxidants. Now plastic-free – this sponge comes in an eco-friendly, FSC-certified cardboard box.
