RESUMEN
BACKGROUND: Both topical and oral probiotics are becoming widely used. There is increasing interest in the cosmetic potential in topical probiotics. Nitrosomonas eutropha is an ammonia-oxidizing bacteria. AIM: The purpose of this study was to assess whether there is any improvement in facial wrinkles with the use of Nitrosomonas eutropha, a topical probiotic. METHODS: In this prospective study, high-resolution photographs were obtained in twenty-nine participants at baseline and after using topical Nitrosomonas eutropha for seven days. RESULTS: There was a significant difference in wrinkle depth and severity in the high concentration probiotic group. There was also a statistically significant improvement in pigmentation of the forehead and glabella in the higher concentration group. CONCLUSIONS: Nitrosomonas eutropha may have aesthetic benefits in terms of reducing the appearance of wrinkles. Larger studies with longer treatment and follow-up periods are required.
