Abstract: Solar radiation causes damage to human skin, and photoprotection is the main way
to prevent these harmful effects. The development of sunscreen formulations containing nanosystems
is of great interest in the pharmaceutical and cosmetic industries because of the many
potential benefits. This study aimed to develop and evaluate an octyl methoxycinnamate (OMC)
liposomal nanosystem (liposome/OMC) to obtain a sunscreen formulation with improved safety
and efficacy by retaining OMC for longer on the stratum corneum.
