The downstream effects most consistently described in the literature: induction of collagen I and III, elastin, and decorin synthesis (Maquart et al., FEBS Letters , 1988), upregulation of VEGF and basic FGF transcripts, induction of antioxidant defense genes including SOD2 and metallothionein isoforms, and modulation of the MMP-2 and TIMP-1/2 balance toward non-fibrotic remodeling
These products may not meet pharmaceutical quality standards and could pose safety risks
From boosting collagen to repairing damaged tissue, reducing inflammation, and reducing the effects of environmental factors
For topical use: trial data shows measurable skin parameter changes (elasticity, fine lines, hydration) at 8 to 16 weeks of consistent use
