Study of product effects on the production of collagen neo-synthesis in human fibroblasts.
Report: In Vitro Clinical Study
At the request of the INSTITUT D’EXPERTISE CLINIQUE – ESPAGNE, we have evaluated the effect of Living Silica ® in the following parameters:
Evaluation of Cytotoxicity
The results are presented in the following table:
Optical density | % | |
(570nm) | ||
Negative Test | 0.512 ± 0.03 | - |
Living Silica ® (0.2%) | 0.508 ± 0.04 | ns |
Living Silica ® (0.5%) | 0.500 ± 0.06 | ns |
Living Silica ® (1%) | 0.514 ± 0.04 | ns |
NS: Not Significant |
The results show that Living Silica ® does not present cytotoxicity with regard to any human fibroblasts in culture when used to 0.2%, 0.5%, and 1.%.
Evaluation of the Collagen Index
The separation and identification of hydroxyproline were performed by reversed-phase HPLC. Fluorescence peaks, after integration, used to calculate the concentration of hydroxyproline in the medical culture.
Concentration of hydroxyproline (mg/ml) | % increase | |
Negative Test | 1.64 ± 0.10 | - |
Living Silica ® 0.2% | 1.79 ± 0.13 | 9 |
Living Silica ® 0.5% | 1.86 ± 0.08 | 13 |
Living Silica ® 1% | 1.95 ± 0.10 | 19 |
The results show that Living Silica ® significantly increments the level of collagen produced by the human fibroblast cultures by comparison with the control.
Conclusion
In the experimental conditions adopted for the product Living Silica ® :
In conclusion, the Living Silica ® product induces a significant increase in the index in cultured human fibroblasts.
