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 help keep your microbiome's community of microorganisms balanced, which is essential to maintaining a healthy skin barrier. Probiotic skincare is an emerging field focusing on introducing live beneficial bacteria to skincare. Research is ongoing, but many users report positive results, particularly those with sensitive or reactive skin. Ensuring you take an oral probiotic or eat foods naturally rich in probiotics (such as kefir, kombucha or kimchi) will help support your skin microbiome. Using prebiotic-enriched skincare (or taking an oral prebiotic) will also help probiotics flourish within your body.
