Chronic exposure to ultraviolet (UV) radiation induces photo‐oxidation, which in turn causes the overproduction of matrix metalloproteinases (MMPs) and collagen degradation. These symptoms are referred to as photoaging, which is characterized by skin thickness, irregular pigmentation, elastosis and coarse wrinkles. In this study, the protective effects of oleracone C isolated from Portulaca olerace against UVB‐induced changes in MMPs and type I procollagen production were investigated in human keratinocytes.
