Brightening Moisturizer

The moisturizer whitening is very good, but I don’t understand if you stop your face to get a duck again so please a few people can tell me why is that happening? Thank you.

The first one I purchased was more strong. This is my second one. It’s not strong. I noticed the first one was darker green. This one was a lighter green & a little weak. It’s not bleaching my skin like the first one was.

I love the way it evens out my skin tone. I also noticed that it tightened my pores in conjunction with the glutathione cleansing bar. Will continue to order.
