This improvement stems from the compounds ability to promote skin regeneration while reducing hyperpigmentation and sun damage

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)

In a small study involving older individuals, two weeks of supplementation with a combination of N-acety-l-cysteine (NAC) and glycine raised red blood cell (RBC) glutathione levels more effectively than either amino acid alone (Guthikonda, et al American Geriatrics Society,Annual Scientific Meeting, 2006.)
Senescent cells accumulate over time and are characterized by altered gene expression, resistance to apoptosis, and secretion of inflammatory mediators collectively referred to as the senescence-associated secretory phenotype (SASP)
