| Résumé : |
Multiple internal and external factors make that the passing years have a deteriorating effect on the skin. The ageing-induced reduction and alteration of essential elements (HA, collagen and elastic fibres...) of the ECM in the skin results in dehydration and volume loss, which translates into wrinkles in the perioral area like nasolabial folds and lipstick lines.
Knowing that bacterial ECPSs from extreme marine environments present special properties, Lipotec studied the efficacy of two biotechnological ingredients, saccharide isomerate and pseudoalteromonas ferment extract, in reducing the visible facial wrinkles cause by the passing years and getting a younger skin appearance. The first ingredient proved to increase HA synthesis (by 66.0%) in HDFa) and decrease wrinkle depths (maximum depth by 13.6% and average depth by 14.7%) in the nasogenian folds in just 14 days, showing superior results after 28 days, showing superior results after 28 days (19.6% and 18.5%) respectively).
Additionally, the average circumference, area and volume were also reduced after 28 days ( 15.3%, 17.2% and 27% respectively), all being statistically significant results.
Pseudoalteromonas ferment extract demonstrated to induce the synthesis of essential dermal proteins like type I collagen (by more than 100% in HDFa) and reduce the roughness of lipstick lines (by 16.5% and 21.5% versus initial time after 7 and 28 days.
Therefore, the combination of such ECPSs obtained by biotechnology improves one of the most concerning facial areas in mature skin, minimising lipstick lines and nasogenian folds by replenishing them, which implies a rejuvenated facial aspect. |
