This product is designed to be a \”cell turn over\” product. It used to come in a lighter weight formula but not it has added benefit of moisturizer. I use this at night before bed and after I wash my face. It is also designed to be used with a booster moisturizer like the Moisture Surge but I find that most of the time this is enough and I use the Moisture Surge in the AM. This product is designed to speed up cell turnover so healthy cells continue to come to the surface quicker. This helps by loosening the dead skin cells at the surface. It helps with clarity and texture issues as well.
