Across 10 studies, all reported beneficial effects on skin hydration from Lactobacillus brevis SBC8803, with predominantly small to moderate effect sizes. The strongest evidence comes from 2 randomized controlled trials (one with 126 adults and one with 60 women) showing marginal improvements in transepidermal water loss and corneal hydration, though only one study reached statistical significance. Doses and durations were not consistently reported, but the primary RCT used 25-50 mg/day for 8-12 weeks in adults with mild dry skin.
Dose: 25-50 mg/day
