Having previously tried similar products from Dermalogica and Humanrace I can say that this polish is seriously effective and getting rid of blackheads after one use left my skin looking smooth.... with no redness - which is important to me as I have fairly reactive, oily skin and easily prone to redness. You get a lot of product, so only use about half a tea spoon as it foams up quite a bit when you add water. Will I continue using this? Definitely for my Sunday facial days. Drawbacks - not overly keen on the smell of the powder but otherwise a great product :) This is the kind of thing that makes an easy Birthday gift, too.
