Not effective, inconvenient. [SEP] Did not do any lightening, as it says. It's uncomfortable to keep on the face, as it is very thick and does not absorb into the skin at all. Each pod holds a lot of product, impossible to use it all in one application. So I have to store the rest somehow. Problem is after the cover is ripped off, it's very unsanitary to leave it uncovered. Overall, it doesn't do what it claims, and neither is it convenient to store. Really not sure what this product does.
