I will take Aztec Secrets: Indian Healing Bentonite Clay Mask (£9) to the grave, and since a tub of the stuff lasts so long, it'll probably mean I only need about 4 in my lifetime. The cupboard classic has aided me in my poorest hours and my skin will always welcome it's healing effect. Though some might recommend to mix it with apple cider vinegar, my sensitive skin prefers water. — Lucy Kenny, assistant editor, social media and trending
