Pentaxyl may help to decrease the appearance of deep wrinkles and furrows, and to support natural collagen production and help skin appear firm and thicker. Pentaxyl is a proprietary blend of herbal extracts and the breakthrough formulas of the Matrixyl Complex and Argireline, which reduce the appearance of wrinkles and furrows, help skin look thicker and firmer, and gives the skin a youthful glow. Pentaxyl has harnessed the age-fighting power of 'bio-peptide' technology, with three age-fighting bio-peptides (1) Pamitoyl-Pentapeptide-3 (Matrixyl) (2) Palmitoyl Oligopeptide (3) Acetyl Hexapeptide-3 (Argireline). Peptides are a low molecular weight amino acid group that are building blocks of proteins that make up plants and animals. Palmitoyl_Pentapeptide-3 was discovered at National Institute of Health.
