209 PRP enriched facial lipofilling A B C Figure 5. Changes in average true skin elasticity (R7) and R5-6 parameter, for both groups preoperative and during follow-up measured with Cutometer MPA850 at both locations. Data represents group means with SEM. A: R7 parameter location 1 and 2: true skin elasticity, higher values represent an increase in skin elasticity and a positive effect. There is a marginal increase in both groups, with no significance. B: R6 parameter location 1 and 2: the ratio of viscoelastic to elastic extension. Lower values represent a positive effect. C: R5 parameter location 1 and 2: the net elasticity: Higher values represent a positive effect. Again, a minimal gain in both groups, with no significant differences, between both groups or within each group at every follow-up moment.
