This mask claims to rapidly reduce visible redness, blotchiness and reactivity – the perfect anecdote for my irritable, sensitive skin. The magic ingredient, allegedly, is mushrooms (which you will no doubt have gathered from the name), which Dr Weil maintains are essential for the well-being of your skin, and play a particularly crucial role in the reduction of inflammation.Does it work? No. Or rather, not in the way I expected/wanted it to. The first time I used it I felt like I did see a slight improvement the next day, but I’m not sure if that was just me willing it to work, or if my spots were just on their way out and so were less red anyway. The subsequent times I used it I saw no reduction in redness, and whilst it didn’t prevent me from getting more spots, my skin did feel soft and hydrated. However, this is probably because you don’t wash the mask off, you tissue it off – so it leaves a film of product on your skin.
