Serums are a popular self-care product to keep skin healthy. Formulation ingredients can vary dramatically. Some serums use plant-derived ingredients while others use synthetic oils depending on consumer preferences and needs.
Thus, serum development is a dynamic process requiring a plethora of characterization experiments to differentiate between formulations.
Here we demonstrate that the automated viscometer system, VROC® initium, can perform rate sweeps experiments to characterize different serum formulations based on their rheological properties with minimal engagement.
