Lactococcus ferment lysate Research from 2023 suggests that adding fermented cultures of various probiotic strains to lotion can improve skin barrier function, reduce skin redness and irritation, and boost moisturization in part by helping to prevent transepidermal water loss (TEWL).29 Matrixyl 3000 and Matrixyl synthe'6 According to a 2023 review, in a small study on 24 men, the use of Matrixyl 3000 for two months led to a reduction in wrinkle depth by 10.2% and wrinkle volume by 17.1%.30 Similarly, another small study using a product that included Matrixyl 3000 as an ingredient (among others) found that, by day 28 of use, a majority of participants (75% of 32 total subjects) expressed overall satisfaction with their skin appearance, and a significant decrease in the number, depth, and volume of wrinkles was noted by researchers.30 While its difficult to find research specifically on Matrixyl synthe'6, studies on palmitoyl tripeptide38 suggest that the ingredient stimulates the synthesis of collagen, hyaluronic acid, fibronectin (a protein important for wound healing), and laminin (proteins that play a key role in maintaining the structure of the bodys tissues)

Researchers have studied its effects on tissue repair, angiogenesis, and nitric oxide signaling in preclinical models for more than two decades
Its a waste of time, funding, and intellectual effort
A 2022 editorial review by Sikiric and colleagues in World Journal of Gastroenterology synthesized prior rat work on major vessel occlusion, Pringle-maneuver ischemia-reperfusion, and Budd-Chiari syndrome, framing collateral-vessel recruitment as a proposed mechanism by which BPC-157 may compensate for occluded flow a narrative synthesis that does not itself report original effect sizes or p-values
Research shows it may modulate glutathione pathways and improve detoxification (11)
