| Résumé : |
For the last 20-30 years UV was really the main topic in skin care science. Until recently, people might not have been aware of the detrimentaI effects of environmental pollution on skin mainly because UV was thought to be the one to cause extrinsic skin ageing. Nowadays, people have come to know that pollutants have harmful affects similar to that of UV on skin, and also that pollutants in combination with UV may have greater impact on skin because of the production of ozone from photochemical reactions between the pollutants, heat, and UV. One of the pollutants is tobacco smoke, which is well-known for its harmful effects on health, and another is PM2.5, against which scientists have already declared war all over the world.
People are now looking for solutions to the harmful affects of pollution. We have been conducting exclusive research on environmental factor-induced skin ageing for many years. Among these factors we investigated tobacco smoke and PM2.5's relationship with skin ageing with the aim of developing a natural-based cosmetic ingredient to be used in cosmetic formulations. We could provide one optimistic solution that ougon extract could be an ideal cosmetic ingredient for manufacturers willing to develop an anti-ageing finished product based on skin care against environmental pollution, particularly tobacco smoke and PM2.5. |

- AIR POLLUTION AND ITS MECHANISM OF ACTION
- FIGURES : 1. Inhibition of tobacco smoke (extracted in an organic solvent, hexane)-induced expression of CYP1B1 in human cultured fibroblasts by ougon - 2. Reduction of MMP-1 expression induced by oil (a) and water (b) soluble components of tobacco smoke by ougon - 3. Down-regulation of PM2.5-induced expression of CYP1A1 by ougon in NHEK - 4. Inhibition of PM2.5-induced expression of CYP1B1 in NHEK by ougon - 5. Suppression of mRNA expression of IL-1b induced by PM2.5 in human cultured keratinocytes - 6. Down-regulation of PM2.5-induced expression of IL-6 in NHEK by ougon - 7. Dose-dependent inhibition of IL-8 expression induced by PM2.5 in human cultured keratinocytes by ougon - 8. Ougon significantly reduced the formation of wrinkle (a) and improved skin elasticity (b) on human skin - 9. Ougon decreased pigmented spots as well as melanin index on the faces of smokers significantly |
