Are the results of the Transepidermal Water Loss (TEWL) study statistically significant?
As with most clinical studies sponsored by a supplier, the results reflect a directional trend because of a number of factors, including formulation nuance, the limited number of panelists and the cost of a clinical with sufficient numbers of panelists to draw a statistical conclusion. Every formulation is different. We believe the results are sufficient to merit customer interest to formulate and to justify a clinical study of their own.
