Effective combination of two active ingredients: to sustainably improve the skin structure, the intensive effect of retinol for skin regeneration is supported by biometric Tri-Peptide-1. The stable retinol in it stimulates collagen synthesis and inhibits collagenase, thus supporting natural collagen production in the skin, which is most active at night. This process contributes significantly to skin regeneration, which is further stimulated by retinol. The adjuvant biometric Tri-Peptide-1 activates the essential matrix proteins collagen and elastin for noticeably MORE skin density and firmness. Within one week, the skin texture is improved and fine lines and wrinkles are demonstrably reduced, leaving skin looking more balanced and even.
