Antioxidant capacity of the empty and Rosa canina seed oil-loaded liposomes (non-treated and UV-irradiated) obtained in the ABTS (a) and DPPH (b) assays; IC50, the concentration of the liposomes required to scavenge 50% of the DPPH radicals; values with different letters (a–c) showed statistically significant differences (p < 0.05; n = 3; analysis of variance, Duncan’s post-hoc test).
