Overrated moisturizer and it's expensive
I've used three tubs of this and my skin has gotten worse. The first two I noticed my skin gotten oilier than usual, but I want to trust the process like any other people. But I got a breakout on my third tub so I switched to other products and my skin has gotten so much better. This is definitely not for oily skin that needs sebum control..

Decent retinol product. However it pills a lot and doesn't get absorbed easily. Wouldn't buy again.
Has had the biggest impact in terms of clearning skin and overall skin health.
