this is by far the best mask in have ever used. it is really gentle as most masks i find esp such clay like masks dry out my skin and cause it to burn and peel even before the recommended time is up. i left it on the whole night while i slept and immediately noticed my skin texture improve! the price tag is a bit hefty but worth every cent also the instructions are to apply a thick layer on the face but i got away with applying a thin layer with a foundation brush
