Characterization of the DBP-Lip and DBP-Lip-Gel. (A) The particle size distribution of DBP-Lip measured using dynamic light scattering analysis. Transmission electron microscope images of DBP-Lip with the scale bar representing (B) 200 nm and (C) 1 μm. Scanning electron microscope images of the DBP-Lip-Gel with (D) 2 μm and (E) 50 μm. The arrows mark DBP-Lip uniformly distributed in the hydrogel. (F) The release profiles of different DBP formulations at 37 ℃ for 48 h. (G) The cumulative skin permeation of different DBP formulations. (H) Changes in leakage rate of DBP-Lip stored at 4 ℃ and 25 ℃ for 28 h. (I, J) Changes in particle size, PDI, and zeta potential of DBP-Lip for 28 days. (K) The DBP content of different DBP formulations stored for 6 months. (L) Visual appearance of DBP-Lip-Gel at predetermined time points of 0, 2, 4, and 6 months at 4 ℃. Data are expressed as the mean ± standard deviation; **p < 0.01 DBP-Lip-Gel compared to the DBP-Lip group, **p < 0.01 and ****p < 0.0001 compared to the DBP group, n = 3.
