Shishedo's cle de peau anti-age spot serum?

I recently started to use Shishedo's White Lucent Brightening Serum as I saw some recommendations from here. It worked really well for me. I was hardly expecting any results, but the difference was quite noticeable after just a couple of days. Today I went to the store intending to buy the serum, but somehow bought the cle de peau anti-age spot serum instead. The reason was that the sale rep was a 54 year old lady with almost no dark spots, and she said she uses cle de peau. However as I leaving, she also bid me to be patient and not to expect results too soon.

Has anyone here used the cle de peau anti-age serum? Does it work well? I'd appreciate some feedback, as I also noticed that this is not a concentrated serum, as the White Lucent line serum is.

Thank you so much!
