April 2020 in “Dermatology and Therapy” In this randomized double-blind study, 160 adults with alopecia areata showed significant improvements in hair loss severity after using a bioactive peptide cosmetic product that mimics platelet-rich plasma, while the placebo group showed no significant change, underlining the treatment's potential effectiveness.
September 2023 in “Clinical, cosmetic and investigational dermatology” In this study, the researchers found that a 28-day topical treatment with a postbiotic ferment complex notably altered the scalp microbiome in women with sensitive scalps, increasing certain bacterial species and decreasing others, while also reportedly alleviating symptoms of sensitive skin syndrome in all participants.
February 2026 in “Cosmetics” This study found that upcycled postbiotic cell-free supernatants from Limosilactobacillus fermentum MG901 and MG4237 protected human dermal papilla cells from oxidative stress, enhancing wound-healing capacity and mitochondrial function, suggesting potential as a sustainable cosmetic ingredient for hair loss alleviation.
February 2026 in “International Journal of Clinical Dermatology” This review found that microbiota-targeted interventions, particularly certain strains of probiotics, are associated with improvements in skin conditions, most notably in pediatric atopic dermatitis, but their efficacy varies across other dermatological diseases.
August 2026 in “Frontiers in Immunology” This review explores the emerging role of postbiotics—such as inactivated bacteria, cell components, and metabolites—in enhancing wound healing and skin microbiome health, highlighting evidence from various preclinical and preliminary clinical studies.
