NAD+
Summary
Palmitoyl Dipeptide-6 is a synthetic dipeptide (lysine-threonine) with a palmitoyl fatty acid tail, designed to penetrate the skin barrier and stimulate the extracellular matrix components essential for skin firmness. It activates fibronectin and type IV collagen synthesis, improving skin density and firmness particularly in mature or sagging skin.
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in all living cells that declines dramatically with age. It is critical for energy metabolism, DNA repair, and sirtuin activation. IV and subcutaneous NAD+ supplementation is used in anti-aging protocols and addiction recovery programs.
