Assessment of storage stability of liposomes, ethosomes and geraniol-ethosomes stored for 90 days at room temperature: (A) Mean diameter; (B) Polydispersity index; (C) Zeta potential. Mean values ± standard deviations are reported (n = 3). For each group (mean diameter, polydispersity index, zeta potential), the same letter indicates values that are not statistically different from each other (p > 0.05).
