The biggest difference between Cellbrick Cream and Lotion is the difference between the oiliness and the feeling of applying.
The cream has a little bit more heavy than lotion and has more oil. With this difference, the cream is used for dryness and narrow areas, and the lotions are used for the whole body including the face and the hot iron such as wide area or summer.
You do not need to use both products together on the same part. If you have systemic dry skin, you can apply a lotion for the body, and you can use a cream on your face or the back of your hand for more dry and narrow areas.
Occasionally, if you have a general sense of dryness, you can use Cellbrick Cream in your whole body.
