Silab has launched Revilience, a natural active ingredient derived from the Sphingomonas panaciterrae bacterium claimed to restore the skin's so-called vitality signature.
This is achieved, says the French manufacturer, by regulating biological pathways linked to the metabolism and protection of cutaneous cells.
After seven days of treatment at 2.5% dosage, it adds, the complexion's radiance is sublimated, and hydration is improved.
Sphingomonas panaciterrae bacteria is present in the ginseng rhizosphere, where it deploys protective mechanisms via the production of sphingane-type exopolysaccharides (EPS).
Silab consequently developed a biotechnological process of controlled nitrogen deficiency applied to Sphingomonas panaciterrae, which doubled its EPS production compared with a non-deficient process.
Coupled with a specific enzymatic hydrolysis, this unique bio-inspired approach resulted in an active ingredient composed of oligosphinganes of interest, capable of improving the metabolism of skin lacking vitality.
Relying on solid scientific expertise based on transcriptomics, Silab established the gene mapping of skins subjected to nutritional deficiency (growth factor depletion) or physiological deficiency (ageing), thanks to an unprecedented modeling study.
These two deficiency conditions revealed a common degradation of epidermal cell metabolism and protection mechanisms.
By reactivating these biological pathways in deficient skin, Revilience restores the skin's ‘vitality signature’. Cellular metabolism is thus stimulated, and the quality of the cutaneous barrier reinforced.
Revilience is a patented natural active ingredient, recommended in all skincare products for skin lacking vitality at a dose of 0.5 to 2.5%.
Available in an aqueous solution, it is easy to formulate. It complies with biodiversity regulations and has a natural origin content of 98.8% (ISO 16128). It conforms with international cosmetics regulations (Europe, USA, China, Japan, and more).
