Efficacy of a Postbiotic Formulation Combined With Microneedling for Mild‐to‐Moderate Acne: A Self‐Control Study

Résumé fourni par la source

BACKGROUND: Acne vulgaris significantly affects young individuals globally, with its onset associated with an increased prevalence of C acnes, a naturally occurring skin bacterium. In light of the rising concerns regarding antibiotic resistance and the potential for adverse effects, pharmacological interventions may not consistently represent the most suitable option. Nonpharmacological approaches, such as microneedling, offer promising alternative treatment modalities. Furthermore, the integration of postbiotics in skincare formulations for acne management has gained traction recently. Nonetheless, there remains a lack of sufficient evidence to establish the efficacy and safety of postbiotics when combined with microneedling. OBJECTIVE: To assess the clinical effectiveness of a postbiotic formulation combined with microneedling in mild-to-moderate facial acne vulgaris. METHODS: Twenty Chinese patients were enrolled, all received one treatment and were monitored 4 weeks posttreatment. The evaluation assessed symptom improvement, treatment safety, and patient satisfaction. RESULTS: The global acne grading system (GAGS) score decreased more than half based on the baseline. Clinical photographs following treatment revealed improved the skin lesions and brightened skin tone. Statistics from VISIA showed excellent improvement in speckle, pore, red region, and porphyrin. No significant adverse reactions have been reported during the treatment period. Additionally, more than 85% were very satisfied or satisfied with the outcome. CONCLUSION: Our results showed that the postbiotic formulation combined with microneedling may benefit the restoration of the skin barrier and the equilibrium of skin microbiota. This approach may help mitigate inflammation and address skin lesions, presenting a promising therapeutic avenue for the prevention and management of acne vulgaris.
