not effective inconvenient [SEP] did not do any lightening as it says it is 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 is very unsanitary to leave it uncovered overall it does not do what it claims and neither is it convenient to store really not sure what this product does
