Prebiotics
Prebiotics are ingredients that feed the good bacteria already living on your skin, helping to keep your skin’s microbiome balanced and healthy. Think of them as fertiliser for the friendly microbes that protect your skin barrier. They are becoming a popular addition to gentle, modern skincare formulas.
How it works in skincare
In cosmetics and skincare, prebiotics such as fructooligosaccharides or inulin work by selectively nourishing beneficial microorganisms on the skin’s surface while discouraging the growth of unwanted ones. This helps reinforce the skin’s natural microbiome, supporting a stronger barrier, smoother texture and calmer appearance. They are frequently found in cleansers, serums, moisturisers and masks aimed at sensitive or stressed skin.
