The interactive solution to harmful urban pollution

H&PC Today

To combat pollution, a true enemy of the skin, SILAB is offering MITOKINYL®, an anti-pollution natural active ingredient rich in glucomannans and able to combat harmful environmental stress via a unique regulation pathway.

SILAB Research is the first laboratory to identify the central role of mitokines in an optimum antipollution strategy. Thanks to a sophisticated intracellular communication mechanism, these mediators, released by mitochondria under the effects of pollution, connect the skin to its environment and initiate an appropriate anti-stress response.

During a pollution attack, MITOKINYL® :
• regulates the two major biological pathways of pollutant stress response: the synthesis of mitokines (prohibitines) is normalized and the aryl-hydrocarbon receptor is deactivated;
• forms an effective, stratified, functional barrier;
• optimizes complexion tone and radiance in Caucasian and Asian volunteers.

MITOKINYL® protects fragile skin against urban stresses and is recommended in all antipollution facial and body skincare products.

MITOKINYL® restores the mitokines pathway
Study in vitro on SILABSKIN® RE reconstructed epidermis.

Modeling in vitro has shown that stresses resulting from pollution cause a significant reduction in the synthesis of mitokines (prohibitins) by human keratinocytes. This reduction is due to the direct effect of pollutants (benzo[a]pyrene: -12%; particulate matter PM: -15%) but is also due to a consequence of pollution (reduction in the oxygen content of air: -37%).
When subjected to an environment mimicking the consequences of pollution, the synthesis of prohibitin by SILABSKIN® RE is significantly reduced by 28%. Tested at 0.25% in this model, MITOKINYL® significantly restores the synthesis of prohibitin by 58%, thereby ensuring the maintenance of intracellular communication among partner organelles and the triggering of a suitable anti-stress response.

MITOKINYL® favors the construction of a stratified and functional epidermis
Study in vitro on SILABSKIN® RE reconstructed epidermis.

When faced with a pollution incident, the epidermal construction and the synthesis of epidermal differentiation markers, cytokeratin 10, filaggrin and loricrin, are significantly reduced.
Tested at 0.25% in this model, MITOKINYL® significantly restores the epidermal construction by 63% (see figure) and the synthesis of cytokeratin 10, filaggrin and loricrin by 45%, 52% and 69%, respectively.

MITOKINYL® revitalizes the recuperation capacity of the skin barrier
Tewameter study in vivo.

MITOKINYL® improves the recuperation capacity of the barrier function of the skin. In only 4 days, MITOKINYL® restores the barrier effect to more than 90%, in contrast to the placebo zone that requires 7 days before observing total recuperation. The difference is significant after only 1 day.

MITOKINYL® inhibits melanogenesis
Study in vitro on cultures of melanocytes.

Tested at 1%, MITOKINYL® significantly reduces the quantity of melanin synthesized by B16F1 melanocytes by 38%, and that synthesized by human melanocytes by 43%.

MITOKINYL® improves skin complexion
– Complexion radiance and the Caucasian panel
Study in vivo on Caucasian volunteers.

After 14 days of twice daily applications, MITOKINYL®, formulated at 3% and in comparison to the placebo, improves parameters of complexion radiance. This effect continues after 28 days of applications.

MITOKINYL® improves skin complexion
– Chromaticity and the Asian panel
Study in vivo(1) on Asian volunteers.

After 28 days of twice daily applications, MITOKINYL®, formulated at 3% and in comparison to the placebo, significantly optimizes parameters of skin color of Asian subjects.
