It has been developed as a probiotic with potential applications in improving overall skin health.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>This study aimed to evaluate the perceived changes in skin quality following topical application of a formulation containing skin commensal probiotic BLIS Q24\u2122.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A 28\u2010day study involving 96 participants with self\u2010reported normal skin with occasional blemishes or breakouts, topically applied a serum formulation containing BLIS Q24\u2122 to the face. Participants quantitatively evaluated the probiotic serum effect on their skin at baseline Day 0 and then again on Day 10, 20 and 28 of the application. In addition, participants maintained a photo diary to record the perceived changes to their skin.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 96 participants completed this research. In comparison to the baseline (Day 0), within 10\u2009days, a significant reduction in blackheads (48%), oiliness (48%), blemishes (57%), dry areas (23%), redness\/rosacea (45%) and flaky and rough skin (38%) were reported. The probiotic serum was also effective in a significant reduction in fine lines and wrinkles (38%), whiteheads (41%), pimples (55%), age spots (29%), and acne (21%) by the end of 28\u2009days of probiotic application. Overall, there's agreement that probiotic serum delivers or exceeds consumer expectations from the concept and performs just as well, or better, than their regular moisturizer.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>An approach of delivering a live probiotic packaged in an innovative formula to improve several skin conditions in otherwise healthy individuals was found to be successful. This study highlights that a serum formulation containing BLIS Q24\u2122 has a positive impact on skin health. It is effective topically in reducing the appearance of skin blemishes, oiliness, wrinkles, redness, and dryness. BLIS Q24\u2122 offers the potential for preventing skin health\u2010related issues and routine maintenance of skin microbiome for healthy skin.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ics.13043","type":"journal-article","created":{"date-parts":[[2025,1,22]],"date-time":"2025-01-22T09:53:50Z","timestamp":1737539630000},"page":"488-496","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Efficacy of a topical live probiotic in improving skin health"],"prefix":"10.1111","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7621-588X","authenticated-orcid":false,"given":"Rohit","family":"Jain","sequence":"first","affiliation":[{"name":"Blis Technologies Limited  Dunedin New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abigail L.","family":"Voss","sequence":"additional","affiliation":[{"name":"Blis Technologies Limited  Dunedin New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Del Rosario","sequence":"additional","affiliation":[{"name":"Kantar  Dunedin New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John D.
