Sabinsa recently published its first human clinical study on anti-acne benefits of LactoSporin, the probiotic metabolite derived from the probiotic LactoSpore. A second published study, in vitro, demonstrated the anti-aging potential of this topical ingredient. Together, the research supports the use of LactoSporin for skin care applications.
Anti-Acne Benefits of LactoSporin
“Novel Topical Application of a Postbiotic, LactoSporin, in Mild to Moderate Acne: A Randomized, Comparative Clinical Study to Evaluate its Efficacy, Tolerability and Safety” by Majeed M, Majeed S, Nagabhushanam K, Mundkur L, Rajalakshmi HR and Shah K was recently published in the journal Cosmetics (Cosmetics 2020; 7(3): 70). The study was conducted as a randomized, open-label, comparative study in 64 human volunteers with mild to moderate acne.
As one of the first systematic clinical studies of a probiotic metabolite, the research demonstrates the efficacy of LactoSporin 2% w/w cream in reducing the severity of acne in human volunteers, with the effects comparable to benzoyl peroxide 2.5% gel.
The anti-acne effects of LactoSporin were observed in as early as three days. The three-week study measured improvement in skin condition based on dermatologist visual assessment and instrumental measurements of acne spots. A significant improvement in all the assessed parameters was observed in both LactoSporin and benzyl peroxide groups.
In addition, a significant decrease in sebaceous secretion was observed for LactoSporin, which resulted in reduced oiliness, pimples, acne spots and redness around the acne spot. Further, LactoSporin was found to be stable at an acidic pH and temperature range of 70 to 90°C, with antimicrobial activity against various pathogenic bacteria, including Cutibacterium acnes.
The study concluded that the efficacy of LactoSporin was equivalent to benzoyl peroxide in the treatment of mild-to-moderate acne lesions and has an advantage over benzoyl peroxide in individuals with oily skin.
The cream was found to be safe and non-irritant in a repeated patch test conducted in 25 healthy individuals, prior to the anti-acne study.
Anti-Aging Potential of LactoSporin
In the second study, “Skin Protective Activity of LactoSporin – the Extracellular Metabolite from Bacillus coagulans MTCC 5856” by Majeed M, Majeed S, Nagabhushanam K, Lawrence L, Arumugam S, and Mundkur L (Cosmetics 2020, 7(4), 76), LactoSporin was evaluated for its role in preserving skin integrity in cultured cells in vitro. It was found to be a powerful antioxidant with reactive oxygen quenching activity, and showed protection against UV-induced cellular damage and inhibited collagenase activity, suggesting its potential use in preventing accelerated aging. LactoSporin was also found to inhibit the activity of the enzyme hyaluronidase, thereby preventing hyaluronic acid fragmentation, the major cause of skin moisture loss. Increased expression of transforming growth factor -β, and hyaluronan synthase in skin fibroblasts, suggests that LactoSporin could keep the skin moisturized and maintain skin firmness. The study concluded that LactoSporin is a skin protective postbiotic with wide application in cosmetic formulations.
“LactoSporin’s non-living microbial cell products possess several advantages over the probiotic itself, especially in skin care,” Majeed said. “It shows biological activity in a non-viable state, are easy to formulate, have favorable physiochemical properties and show improved inflammatory defense.”
