Every person has a unique microbiome made up of trillions of microorganisms, including probiotics. While the importance of these bacteria, yeasts, and fungi in digestive wellness is well known, experts are just beginning to understand the effect probiotics play in maintaining skin health. When applied topically in formulas that also contain prebiotics, which help probiotics flourish, their range of benefits include enhancing hydration, supporting the skin’s barrier, balancing pH, and preventing signs of aging.
