Abstract Background: Treatment of photoaging includes non-prescription cosmeceuticals and prescription products, retinoids. Isotretinoin, an established anti-acne retinoid, is also reported to delay the aging process. However, the drug is reported to be an irritant on skin. Purpose: The present study endeavors to explore the potential of a novel set of biocompatible nano-structured systems of isotretinoin in the treatment of photoaging. Methods: Nano-lipoidal carriers (NLCs) of isotretinoin were developed, characterized and investigated in vivo for anti-aging potential in Laca mice vis-à-vis the marketed products of retinoids. The anti-aging efficacy of NLCs was measured in terms of visual and redox-biochemical parameters in ultraviolet (UV)-irradiated mice. Results: Visual observations revealed that there was no significant change (p < 0.05) w.r.t. erythema, skin sagging and wrinkles in the skin of the animals treated with NLCs formulation compared to the marketed product(s). The malondialdehyde levels were found to be significantly reduced, whereas glutathione levels were increased with the application of NLCs vis-à-vis control and test formulations. The NLCs were able to maintain the normal redox-balance of UV-irradiated skin, and were better tolerated by the animals. Conclusion: The study ratifies enhancement in the efficacy of isotretinoin against photoaging and improved skin biocompatibility after its encasement in novel topical dosage forms.
