Evidence Map

What The Sources Report

• Cutibacterium acnes Propionibacterium acnes 6 7 The pathogenesis of acne is multifactorial, arising from the interplay of increased sebum production, abnormal follicular keratinization, colonization with(formerly), and inflammation with contributions from genetic, hormonal, and environmental factors. [Warp Peyton V. (2026); evidence level 1]
• Limited studies of gut microbiota in patients with acne have identified overall reduced diversity, a higher Bacteroidetes:Firmicutes ratio, enrichment of Proteobacteria, depletion of Actinobacteria, and loss of beneficial genera, includingand. [Warp Peyton V. (2026); evidence level 1]
• We link mechanistic insights with clinical and preclinical evidence and uniquely map molecular functions to dermatologic and trichologic outcomes. [Kaplan N (2026); evidence level 4]
• Lactoferrin is a naturally occurring bioactive glycoprotein that is part of the body's innate immune system and has essential roles in iron metabolism, microbial defense, inflammation regulation, and tissue repair. [Kaplan N (2026); evidence level 4]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

There is at least one systematic-review style source in the current set, so it deserves more weight than single-study evidence. For lactoferrin supplementation acne meta-analysis, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
