Benefits
Reduction in acne severity
An open-label RCT in subjects with mild-to-moderate acne applied 2% LactoSporin cream, producing significant improvements in closed comedones, oiliness, papules, and redness versus a benzoyl peroxide comparator, with better tolerability.
Wrinkle reduction in anti-aging applications
A randomized, double-blind, placebo-controlled study in healthy female participants found LactoSporin cream produced a significant reduction in the visibility of wrinkles around crow's feet, nasolabial folds, frown lines, and facial fine lines versus placebo. Skin texture also improved.
Skin barrier and hydration support
Cell-based and clinical work demonstrate antimicrobial activity, free radical scavenging, and reactive oxygen quenching in human dermal fibroblast cells — supporting a multi-pathway anti-aging effect beyond simple antimicrobial activity. Skin moisture (Corneometer) and water loss (Tewameter) parameters improved with regular use.
Live-cell-free postbiotic advantage
Unlike live probiotic skin products, LactoSporin contains no live bacteria — eliminating concerns about cell viability, formulation stability, preservative incompatibility, and contamination. Bacillus Ferment Filtrate Extract integrates well into standard cosmetic formulations and tolerates the chemistry of typical skincare products.
Mechanism of action
Antimicrobial activity against acne pathogens
LactoSporin contains bacteriocin-class peptides from Bacillus coagulans MTCC 5856 with documented activity against skin pathogens including Cutibacterium acnes (formerly Propionibacterium acnes) and Staphylococcus species. Mechanism involves pH drop in microenvironment, inhibition of microbial biofilm formation, and ion drainage from target microbial cells.
5-alpha-reductase inhibition
In vitro studies of LactoSporin demonstrate 5-alpha-reductase inhibitory activity — the enzyme converting testosterone to dihydrotestosterone (DHT). Topical 5-AR inhibition contributes to acne improvement by reducing sebaceous gland activation and sebum production.
Antioxidant skin protection
Cell-based studies in human dermal fibroblasts showed LactoSporin scavenges free radicals and quenches reactive oxygen species. This contributes to anti-aging effects by reducing oxidative damage to collagen and elastin fibers in skin extracellular matrix.
Clinical trials
Randomized, double-blinded, placebo-controlled study (Majeed, Majeed, Nagabhushanam, Lawrence, Clin Cosmet Investig Dermatol 16:909-918).
70 screened, 56 randomized healthy female participants (28 per group). 10-week application of 2% LactoSporin cream or matched placebo formulation.
All 56 completed analysis. Regular use of LactoSporin cream for 10 weeks significantly reduced visibility of wrinkles around crow's feet, nasolabial folds, frown lines, and facial fine lines compared to placebo. Skin texture improved across multiple instrumental measurements (Antera 3D, Cutometer, Corneometer, Tewameter). Demonstrated postbiotic-driven anti-aging effects beyond simple moisturization.
Open-label, randomized, monocentric clinical study (Majeed, Majeed, Nagabhushanam, et al 2020, Cosmetics 7(3):70, doi:10.3390/cosmetics7030070).
64 male and female subjects with mild-to-moderate acne. Three-week treatment comparing 2% LactoSporin cream vs benzoyl peroxide cream.
Significant improvement in dermatologist-assessed closed comedones (p<0.001), oiliness, redness, and papule count with LactoSporin. Better tolerability than benzoyl peroxide (less stinging, irritation, and dryness). Antimicrobial activity, thermostability, pH stability, and 5-alpha-reductase inhibitory activity confirmed in parallel in vitro work. Note: published in MDPI Cosmetics, not PubMed-indexed.
In vitro mechanistic study (Majeed, Majeed, Nagabhushanam, Lawrence, Arumugam, Cosmetics 7(4):76, doi:10.3390/cosmetics7040076).
Human dermal fibroblast cell cultures and antimicrobial panel testing.
LactoSporin demonstrated antioxidant activity via free radical scavenging and reactive oxygen quenching in human dermal fibroblasts. Antimicrobial activity confirmed against panel of skin microbial pathogens. Established cellular and microbial mechanisms supporting the topical clinical efficacy.
