I bought this in Asia - about $40 USD for 3.7 oz tube. I'm on a constant quest to reduce/work on my freckles/age spots/discloration - while these Asian "whitening" products are not meant to erase them, I think they help with my skin's clarity. I really like this cleanser, except for the "scent" that French products seem to all have. However, it's not that heavy, and a little bit goes a LO-Ong way. I squeeze a tiny bit onto my hands, and it foams like crazy, removes all traces of makeup (those that the makeup remover leaves), and rinses very clean without leaving residue or stripping my skin. I would probably re-purchase, but there is a LOT of the product left in the tube, even though I used it regularly in the 5 months I've had it.
As for the whitening/brightening properties, I'm not sure using this product alone will do it. The very courteous & sweet Lotte SA told me this is a lovely and good cleanser but it's just that - it has very little of the whitening product in it. She said if I really love it, I should stick to it but that I should try other products, too (and gave me TONS of near-full sized samples to try - as in, I Think I can live on the samples alone for a whole year without buying any more products).
