September 2019 in “Journal of biological chemistry/The Journal of biological chemistry” This study found that the retinol dehydrogenases SDR16C5 and SDR16C6 in mice play a crucial role in skin retinol dehydrogenase activity, affecting hair growth and gland functions without impacting survival.
This study found that the RN-Lip co-delivery system enhanced the stability and skin permeation of retinol and niacinamide, leading to improved anti-aging and skin-brightening effects in vitro.
This study found that proretinal nanoparticles, applied topically, are safe and effective for penetration into hair follicles, enhancing retinoid biological activity in the skin while reducing irritation compared to conventional retinal formulations.

January 2018 in “International Journal of Advanced Community Medicine” This study reported the formulation of a new cream combining niacinamide and retinol aimed at reducing hyperpigmentation and providing anti-aging and moisturizing effects. It found that the cream remained stable under various environmental conditions and did not cause skin irritation in patch tests.
This study found that the enzyme encoded by Dgat1 acts as a retinol acyltransferase in murine epidermis, protecting against retinoid toxicity and alopecia by preventing retinol accumulation.
