This review explores the gut-skin axis in rosacea, highlighting how microbiome imbalances contribute to this inflammatory skin condition. Modulating gut and skin bacteria may offer new therapeutic strategies for rosacea patients.
Area of Science:
- Dermatology and Microbiology
- Investigates the complex interplay between the gut microbiome, skin microbiome, and inflammatory skin diseases.
Background:
- Rosacea is a chronic inflammatory skin condition impacting quality of life and mental health.
- Pathophysiology involves immune dysregulation, vascular/nervous alterations, and microbial triggers.
- The gut-skin axis, a bidirectional communication pathway, is implicated in inflammatory skin diseases.
Purpose of the Study:
- To review current knowledge on the microbiome's role in rosacea pathogenesis.
- To explore the impact of the gut-skin axis in rosacea patients.
- To assess the potential of microbiota modulation, including probiotics, for rosacea treatment.
Main Methods:
- Literature review synthesizing existing research on rosacea, microbiome, and gut-skin axis.
- Analysis of next-generation sequencing data and its implications for understanding microbial communities.
- Examination of therapeutic strategies targeting microbial modulation.
Main Results:
- The gut-skin axis in rosacea is underexplored compared to other inflammatory skin diseases.
- Microbiome characterization in rosacea patients requires further investigation.
- Probiotic supplementation shows potential therapeutic benefits, mirroring outcomes in other conditions.
Conclusions:
- Understanding the microbiome's influence on rosacea pathogenesis is crucial.
- Targeting skin and gut microbiota modulation presents a promising avenue for improving rosacea clinical outcomes.
- Further research is needed to elucidate specific mechanisms and optimize therapeutic interventions.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
Defense Mechanism Against Infection
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...
