Matexel
Our comprehensive portfolio of bioactive peptides offers targeted solutions for every skincare need. For structural repair and rebuilding the dermal framework, our collagen peptides and oligopeptides stimulate the synthesis of collagen, elastin, and hyaluronic acid to enhance firmness and reduce wrinkles. To protect against cellular aging, Carnosine provides dual-action defense as a potent antioxidant and a formidable anti-glycation agent, preserving collagen quality. For total skin regeneration, Copper Peptides (GHK-Cu) act as master regulators, accelerating wound healing and remodeling tissue for improved clarity. We also offer specialized solutions like our Hexapeptides, which provide a non-invasive, "Botox-like" effect by relaxing facial muscles to soften dynamic expression lines, and our Tetrapeptides, engineered to reduce under-eye puffiness and dark circles by improving lymphatic circulation.
