Probiotics and chronic inflammatory skin diseases

Summary

This narrative review synthesises available evidence on the application of oral and topical probiotics in dermatological therapy, focusing on their potential mechanisms and therapeutic effects in atopic dermatitis, acne vulgaris, rosacea, and psoriasis. The authors build on established probiotic benefits in gastrointestinal and dental health to explore emerging applications in chronic skin inflammation. The review evaluates both direct topical and systemic oral probiotic interventions in these conditions.

Regional applicability

The review provides general evidence synthesis on probiotic mechanisms and efficacy applicable to clinical practice internationally, including the United Kingdom. Transferability depends on whether specific probiotic strains or delivery methods reviewed are available and licensed in UK clinical and consumer settings.

Key measures

Clinical efficacy of probiotics in chronic inflammatory skin diseases; mechanisms of probiotic action in dermatology

Outcomes reported

Analysis of evidence on mechanisms of action and therapeutic efficacy of oral and topical probiotics in chronic skin diseases, with emphasis on atopic dermatitis, acne vulgaris, rosacea, and psoriasis.

Supporting research

The review explicitly analyses oral probiotics alongside topical probiotics for chronic skin conditions, providing a concrete supplement/gut mechanism link.

Limits: Separate oral from topical preparations and each underlying study design; the abstract does not establish that food intake or a particular probiotic treats skin disease.
