What are prebiotics in skincare?

Prebiotics in skincare are ingredients that nourish and support the growth of beneficial bacteria on the skin, promoting a balanced and healthy skin microbiome. Unlike probiotics, which are live bacteria, prebiotics are non-living compounds that serve as “food” for the good bacteria on the skin, helping them thrive and outcompete harmful bacteria. Here’s how prebiotics work in skincare:

1. Nourishing Beneficial Bacteria

Prebiotics are food sources for the good bacteria on the skin, which are essential for maintaining a balanced microbiome. These beneficial bacteria help protect the skin against harmful bacteria that can cause issues like acne, irritation, and infections. By feeding the good bacteria, prebiotics support a healthy skin environment.

2. Supporting the Skin’s Barrier Function

A well-balanced microbiome, supported by prebiotics, strengthens the skin’s natural barrier. This barrier is vital for keeping moisture in and irritants out. By nourishing the good bacteria, prebiotics enhance the skin’s defense mechanism, helping to retain hydration and protect against external stressors like pollution.

3. Reducing Skin Sensitivity and Inflammation

When the skin’s microbiome is imbalanced, harmful bacteria can proliferate, leading to irritation, inflammation, and conditions like eczema or acne. Prebiotics help maintain microbial balance, reducing the likelihood of these skin issues and calming inflammation.

4. Improving Skin’s Overall Health

By fostering the growth of good bacteria and supporting the skin’s natural defenses, prebiotics help improve the overall health of the skin. This can result in a clearer, more radiant complexion, improved hydration, and better resistance to environmental stressors.

Common Prebiotics in Skincare

Some common prebiotics used in skincare include:

  • Inulin: A plant-derived fiber that feeds beneficial skin bacteria.
  • Fructooligosaccharides (FOS): Derived from plants like chicory root, this helps nourish the skin’s microbiome.
  • Alpha-glucan oligosaccharide: A sugar-derived prebiotic that promotes the growth of friendly bacteria on the skin.

Prebiotics are often used in combination with probiotics and postbiotics in skincare formulations to create a holistic approach to maintaining a balanced skin microbiome.
