Across 6 studies, all reported beneficial effects of Lactobacillus brevis SBC8803 on skin health, with predominantly small effect sizes. The evidence suggests improvements in skin hydration and reductions in transepidermal water loss, particularly in healthy middle-aged and elderly subjects. No dose range or study duration was consistently reported across studies.
- Studied populations: healthy middle-aged and elderly subjects
Caveats: Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). Evidence base is small (only 6 studies) — conclusions should be considered preliminary. None of the included studies reported statistically significant findings, so the effect may be smaller or less reliable than the direction suggests.
