FSS Dermal Moisture Lite PPS works very similar when compared to our FSS Dermal Moisture Complex PF but is considered a more lighter version that does not contain the full set of components such as the Urea and Amino Acids that you would find in the FSS Dermal Moisture Complex PF. Without the Urea and Amino Acids the FSS Dermal Moisture Lite PPS has a significantly lighter color and odor.
