Tripeptides are recognized for their high bioavailability and their potential to improve skin structure, hydration and barrier function. This study evaluated the efficacy of MAXI collagen, a tripeptide-based formulation, through combined in vitro and clinical assessments. In cell models, MAXI collagen enhanced collagen production in CCD 966SK fibroblasts, suppressed melanogenesis-related gene expression (TYR, TYRP1, MITF) in A375 melanoma cells and increased SMPD1 along with key anti-aging and antioxidant markers (SIRT1, NADSYN, SOD3, Parkin) in HPEK keratinocytes, indicating broad skin-enhancing activity across multiple pathways. To validate these effects in vivo, a randomized, double-blind, placebo-controlled clinical trial was conducted in 75 adult participants aged 35-65 years. Participants were assigned to MAXI collagen, normal collagen, or placebo (n=25 per group) and consumed o.. View More»
