Figure 7. Microscopic observation of the elastin expression in the dermal layer on Day 8 (D8) after injection. Increases in the density of the elastin network were observed in the dermis following injection of the 2.6% H-HA/3.2% sorbitol composition, by the heightened intensity of green staining, as compared with the control.
