To evaluate the potential of topical postbiotics in managing inflammatory skin conditions like acne and atopic dermatitis.
Approach:
Key Findings:
Postbiotics may improve skin microbiome, reduce inflammation, and enhance skin barrier function.
In eczema patients, treatment led to reduced disease severity, itching, and improved skin barrier function.
In acne, postbiotics were linked to reduced inflammatory lesions and decreased oil production.
Some studies reported lesion count reductions of 50% to 70% with favorable tolerability.
Interpretation:
Postbiotics could serve as a safe adjunct or alternative to traditional acne and eczema treatments, especially for patients with irritation or resistance concerns.
Limitations:
Variability in study design and size may limit generalizability.
Evidence for postbiotics in rosacea is limited, with no clinical trials identified.
Conclusion:
Postbiotics show promise as a well-tolerated addition to dermatologic treatments, but further research is needed to clarify their role and efficacy in clinical practice.
