Peptide is a small molecule protein, also known as polypeptide or peptide, which is composed of amino acids with a certain sequence connected by amide bonds.

palmitoyl pentapeptide 4 , also known as Matrixyl3000, has the effects of promoting collagen production, anti-free radical oxidation, repair, anti-inflammatory and anti-edema. It was first used by dermatologists with anti-aging ingredients such as vitamin A, claiming that it can act on the dermis, promote collagen proliferation, and complement other moisturizing ingredients to achieve a complementary effect.

What does palmitoyl pentapeptide 4 do for skin?

1. Palmitoyl pentapeptide 4 promotes the activity of fibroblasts by simulating signal molecules in the skin, thereby increasing the production of collagen. Collagen is a key protein to maintain skin elasticity and firmness. It can effectively stimulate the synthesis of collagen and help the skin stay young.
2. Palmitoyl pentapeptide 4 can effectively promote the regeneration of collagen or elastic fibers and hyaluronic acid, and has a good effect on increasing the moisture content of the skin and increasing the thickness of the skin.
3. Matrixyl can also promote the repair of the skin barrier, enhance the skin's ability to moisturize and resist external stimuli. This is especially important for damaged and sensitive skin.

4. It can increase the formation of elastin, glycosaminoglycans and fibronectin, making the skin elastic and achieving the purpose of anti-aging.

In skin care products, peptides have become a very important active ingredient in anti-wrinkle and anti-aging. Pentapeptides are used by international brands for facial lifting and eye care. They are highly hydrophilic, promote the production of hyaluronic acid, and increase the moisture content of the skin. In addition, they are widely used in whitening, repairing, antibacterial, and promoting hair growth.
