Figure 9.

Skin hydration after application of films based on sodium alginate and gelatin with different amounts of glycerol and lipids, as well as the sample with incorporated PLA microparticles. Time = 0 refers to the measurements taken immediately after the removal of films from the skin. The results are the differences in the corneometer indications between the test field and control field at the appropriate point. Significant differences compared to the control samples: ALG/GEL/G (1%) and ALG/GEL/G (10%) for each time were marked on the graphs with (*).
