Résumé : |
The balance between collagen breakdown and collagen synthesis plays a crucial role in the extrinsic and intrinsic process of skin ageing. Environmental factors acting on the skin and genetically-determined processes cause an increase in collagen breakdown and at the same time a reduction in the synthesis of new collagen, which results in the increased appearance of wrinkles. One of the enzymes responsible for the breakdown of collagen is matrix metalloproteinase 1 (MMP-1). It has been demonstrated that an extract of pomegranate flowers reduces MMP-1 mRNA gene expression in UVA irradiated and non-irradiated primary human dermal fibroblasts. Due to this characteristic, the pomegranate flower extract (PGFE) was combined with sodium ascorbyl phosphate (SAP) into a single product (PGFE/SAP). SAP, a derivative of vitamin C, is a wellknown antioxidant and collagen booster. The combined product made of PGFE and SAP (PGFE/SAP) was successfully tested for its safety in use both in vitro and in vivo. Results showed that PGFE/SAP promoted collagen synthesis, reduced the breakdown of collagen and measurability and visibly reduced the depth of facial wrinkles caused by skin ageing. |
