Matrixyl 3000? Matrixyl 3000 contains 2 peptides Pal-GHK and Pal-GQPR. These two peptides (aka matrikines) mimic the appearance of broken down collagen, signaling your body to produce more collagen and elastin. A lack of collagen and elastin is directly linked to the early signs of aging. Fortunately, we have matrixyl 3000 which helps to counter those effects and actually increases their production. What is Hyaluronic Acid? Hyaluronic acid exists naturally in our connective, epithelial and neural tissues. It is the main component of our extracellular matrix. The epidermis is a sponge-like matrix that contains spaces filled with water, protein and hyaluronic acid. Hyaluronic acid attracts and retains water in this matrix, which is what plumps out your skin, diminishing the appearance of fine lines and wrinkles.
