This is must have product. I have received a sample first, and than I bought big side. The polisher works better than scrub, works on microlevel. the skink looks so good (but something red too) after. I use this polisher before peeling mask, and finalise with moister mask. Be very carefully, as due to structure it really takes away old dead skin and impurities and everything from your skin. It is easy to polish face until the micro scratches or cut. Not sure about sensitive skin. I have combination, and really like the product, a bit pricy, but in this case highly valued by me. Before I did at least two peels a week, now after this polisher one time is enough.
