Table 2. Placebo products used for in vivo studies to test the PN complex in a cream, and the EG complex in a gel

After skin irritation was induced, test formulas (see Table 2) were applied blindly following their usual use to volunteers. In the first group of volunteers, four of the irritated areas were treated with a water-based gel containing the EG complex at varying concentrations; in the second group of volunteers, four irritated areas were treated with a cream containing the PN complex at different concentrations.
