Abstract:
The term probiotic has been defined by experts as live microorganisms, which when administered in adequate amounts, confer a health benefit on the host. Probiotics are, thus, by definition, live microorganisms, and the viability of probiotics is a prerequisite for certain benefits, such as the release of metabolites at the site or adhesion properties, for example. However, some semi-active or non-replicative bacterial preparations may retain a similar activity to the live forms. On cosmetic, lysates or fractions are generally used. Topically applied Vitreoscilla filiformis extract has shown to have some similar biological activity of probiotics in the gut, for example, regulating immunity by optimisation of regulatory cell function, protecting against infection, and helping skin barrier function for better recovery and resistance. Due to their mode of action and efficacy, V. filiformis extract (lysate including membrane and cytosol) may be considered as non-replicative probiotic fractions, and this review article presents all its properties.
Insights
Vitreoscilla filiformis extract, a non-replicative probiotic fraction, demonstrates immune regulation and skin barrier enhancement. This topical application offers benefits similar to live probiotics for skin health.
Area of Science:
- Dermatology and Microbiology
- Skin barrier function and immunology
Background:
- Probiotics are live microorganisms conferring health benefits.
- Viability is key for probiotic efficacy, but non-replicative forms can retain activity.
- Topical application of bacterial extracts in cosmetics is gaining traction.
Purpose of the Study:
- To review the properties and potential of Vitreoscilla filiformis extract as a non-replicative probiotic fraction for topical use.
- To highlight its biological activities relevant to skin health.
Main Methods:
- Review of scientific literature on Vitreoscilla filiformis extract.
- Analysis of its biological activities, including immune modulation and skin barrier support.
Main Results:
- Vitreoscilla filiformis extract exhibits probiotic-like activities, including immune regulation and enhanced skin barrier function.
- It aids in skin recovery, resistance, and protection against infection.
- The extract functions as a non-replicative probiotic fraction.
Conclusions:
- Vitreoscilla filiformis extract is a promising non-replicative probiotic fraction for cosmetic applications.
- Its topical application offers significant benefits for skin health and resilience.
