I have senstive skin prone to occasional break-outs. Prior to trying this clay mask, I was using St Ives Mineral Clay Firming Mask about once per week. I found the mask made my skin feel clean and soft after use and did a great job bringing impurities to the surface. I switched to this Boots Botanics to try a product with more natural ingredients. I found that this mask performs just as well as the St Ives Mask. Since the product does not have added fragrance, the smell of the clay could be unpleasant for some, but it did not bother me enough that I would stop using it. The formulation is also thinner (more watery) than the St. Ives mask, so it was slightly more difficult to apply but again not enough that I would stop using it. All in all I am pleased with the product and plan to continue using it at least weekly.
