111Skin's Sub-Zero De-Puffing Eye Masks are a fan favourite, so it's no surprise it decided to launch a version for your entire face. 111Skin Sub-Zero De-Puffing Energy Facial Mask (£20 for one mask) promises to bring life back to dull, lacklustre skin that's become dull and lacklustre due to stress and fatigue. The sheet mask (which is biodegradable, BTW) is soaked in a serum full of various peptides and caffeine that, after 20 minutes, helps make skin look firmer, fuller, and like you haven't been trying to precariously balance homeschooling and working from home.
