FIGURE 2.

Improvement in skin protection from flexural (non‐axial) forces quantified by the ratio γ for a range of skin elastic moduli (100‐150 kPa) and application of cyanoacrylate liquid skin protectant (CLSP) coating with thickness of 25‐μm post‐polymerisation. The predicted improvement is highly non‐linear and rises substantially for thinner (more fragile) skins such as elderly skin with thickness values lower than ~0.7 mm. An especially thin and fragile (aged) skin region (thinner than ~0.7 mm) which is treated with the CLSP may approximately double its stiffness for resisting flexural distortions with respect to an untreated skin region, thereby allowing treated skin regions to more effectively tolerate localised compressive forces and pressures from a contacting medical device or object. The plotted grey range of γ data resulted from calculations of the γ ratios for the aforementioned range of skin elastic moduli at each skin thickness level
