Quick Answer
Probiotics Rosacea Meta-Analysis has evidence relevant to strength of evidence and what the studies can or cannot prove, but conclusions should stay close to the cited sources. One representative finding is: controls, Skin Barrier Dysfunction Tight junction proteins (claudin-1), ceramides 12 13 12 21 Increased sensitivity, elevated TEWL;,claudin-1 expression reduced by ~50% in rosacea epidermis, Microbial Dysbiosis Demodex folliculorum, B.
Key Takeaways
- 01controls, Skin Barrier Dysfunction Tight junction proteins (claudin-1), ceramides 12 13 12 21 Increased sensitivity, elevated TEWL;,claudin-1 expression reduced by ~50% in rosacea epidermis, Microbial Dysbiosis Demodex folliculorum, B. [Shi Lei (2026)]
- 02: TLR2, Toll-like receptor 2; KLK5, kallikrein-related peptidase 5; hCAP18, human cationic antimicrobial protein 18; LL-37, cathelicidin-derived peptide; NF-κB, nuclear factor κB; NLRP3, NOD-like receptor thermal protein domain-associated protein 3; JAK/STAT, Janus kinase/signal transducer and activator of transcription; mTORC1, mammalian target of rapamycin complex 1. [Shi Lei (2026)]
- 03Hormones, as central messengers linking the brain, gut, and skin, have not been sufficiently integrated with respect to their differential regulatory roles across subtypes; likewise, subtype-specific treatment strategies grounded in the neuro-hormone-immune network lack systematic synthesis of clinical evidence. [Shi Lei (2026)]
- 041 2 3 4 5 6 Rosacea is a common chronic inflammatory skin disease primarily affecting the central facial region, characterized by persistent erythema, paroxysmal flushing, capillary telangiectasia, inflammatory papules, and pustules. [Shi Lei (2026)]
The current Migaku evidence database contains 2 reusable source documents for Probiotics Rosacea Meta-Analysis. This answer focuses on strength of evidence and what the studies can or cannot prove.

- Cross-kingdom bacteria-fungi correlations were weak and nonsignificant.ConclusionsRosacea is associated with distinctive cross-kingdom microbiome alterations, featuring increased bacterial diversity and profound fungal reorganization. [Tang X (2026); evidence level 4]
Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
