What This Ingredient Does

Probiotics are live beneficial microorganisms that help maintain a balanced gut microbiome. A healthy gut microbiome plays an important role in regulating immune responses and inflammation.

Through the gut–skin axis, probiotics can influence skin health by helping reduce systemic inflammation and supporting overall skin balance. This may be beneficial in conditions such as acne and sensitive skin.

Probiotics are often used alongside prebiotics and nutrients that support gut health to improve overall digestive and skin function.
