Here, we evaluate immediate skin responses as clinical endpoints for needle-free jet injector treatments. Methods We injected methylene blue in ex vivo human skin using an electronically-controllable pneumatic injector (EPI; 3-6 bar, 50-130 mu l; n = 63), and a spring-loaded jet injector (SLI) with fixed settings (100 mu l; n = 9). We measured the immediate skin papule (3D-camera), residual surface fluid (pipette), dermal dye distribution by estimating depth and width, and subcutaneous dye deposition. Results EPI with 4 bar and 100 mu l resulted in the largest skin papule of 48.7 mm(3) (35.4-62.6 mm(3)) and widest dermal distribution of 8.0 mm (5.5-9.0 mm) compared to EPI with 6 bar and 100 mu l (p < 0.001, p = 0.018, respectively). The skin papule volume showed a significant moderate to high positive correlation with the width and depth of dye distribution in the dermis (r(s) = 0.63, r(s) = 0.58, respectively; p < 0.001 for both correlations).
