Figure 10.

Skin barrier quality (transepidermal water loss—TEWL) 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. The control measurements were performed before the application of materials to the skin, whereas time = 0 refers to the tests taken immediately after removal of the films that had been applied to the skin for 10 min. 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 (*).
