To understand prebiotics you first need a brief understanding of probiotics. Probiotics are "good bacteria" - bacteria that are beneficial for your body.
When there is an abundance of good bacteria, they can better keep harmful bacteria under control. Probiotics are important for your skin as they help keep your microbiome's community of microorganisms balanced, which is essential to maintaining a healthy skin barrier. Prebiotics are food for these bacteria, which stimulate their growth. Prebiotics can be taken in oral form (whether supplements or as part of your diet) or topically, via skincare products enriched with microbiome-nourishing prebiotics such as inulin, xylitol, oligosaccharides and rhamnose.
