Science
Mechanism of Action
This low molecular weight peptide adeptly penetrates the stratum corneum, stimulating the endogenous production of collagen and elastin to improve skin structure. It mitigates skin damage by inhibiting inflammatory cytokines, thereby reducing redness and irritation. Also recognized as Chronogen®, Tetrapeptide-26 optimizes the skin's intrinsic circadian rhythm by activating critical genes—CLOCK, BMAL1, and PER1—within keratinocytes. This action fortifies cellular defense, boosts DNA protection against UV and environmental aggressors, and enhances natural DNA repair processes, particularly during nighttime. It promotes keratinocyte survival under stress, strengthens the skin barrier function, and provides antioxidant benefits by scavenging free radicals, ultimately contributing to a smoother, softer, and more hydrated skin texture.
