This is a body lotion I purchased at a dermatologist's office when I was suffering from dermatitis. I knew about Cellfusionc because their BB cream is famous, but this was my first time trying their body lotion. It has a large capacity and good ingredients, so I apply it all over my body. In the fall or winter, I sometimes apply it to my face as well. They say it helps with the skin barrier, and while I'm not sure about the barrier aspect, my skin definitely seems to have improved. I think I apply it whenever my skin gets worse.
