Objective:

To evaluate the potential of topical postbiotics in managing inflammatory skin conditions like acne and atopic dermatitis.

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.
