Palmitoyl Tetrapeptide-7

Short Description:

Palmitoyl Tetrapeptide-7 is also called Palmitoyl Tetrapeptide-3. Palmitoyl Tetrapeptide-7 is a synthetic peptide comprised of four amino acids that is used in beauty products and cosmetics to suppress the production of excess interleukins, the chemical messengers which trigger the body’s acute inflammatory response. This can lead to glycation damage, or the process by which glucose links with proteins and causes them to bind together, stiffening tissues. This negatively affects the skin’s support system, comprised of collagen, elastin and other proteins, and leads to wrinkles, sagging, and uneven skin tone (Source).

    Palmitoyl Tetrapeptide-7/Palmitoyl Tetrapeptide-3 can suppress the production of excess interleukins, therefore inhibiting unnecessary inappropriate inflammatory responses and glycation damage.Palmitoyl Tetrapeptide-7/Palmitoyl Tetrapeptide-3 has been used in beauty products and cosmetics to reduce the cumulative amount of damage that occurs following exposure to UV light, pollution, internal stress, and other pro-inflammatory factors.It is used to counteract skin slackening and to perk up and increase the firmness of the fragile skin area around eyes.

    Science has proven that peptides can help manage wrinkles in your skin and reverse the signs of aging.
    Human skin is comprised mostly of collagen. Collagen is a protein comprised of long segments of amino acids arranged like a chain. Collagen provides a foundation and thickness for skin.
    Women under 30 have ample collagen, which results in smooth, tight skin.
    The rest of us have less collagen – skin tends to be thinner, revealing more wrinkles.
    When collagen breaks down, short segments of amino acids are formed. These are the tiny proteins and active molecules known as peptides. Peptides in skin care can provide significant anti-aging benefits.

    1.Palmitoyl Tetrapeptide-7/Palmitoyl Tetrapeptide-3 mimics the activity of DHEA, the youth hormone that functions to reverse IL-6 over
    -production, and therefore reduce the aging symptoms as well as the phenomenon of immunosenescence.

    2.Palmitoyl Tetrapeptide-7/Palmitoyl Tetrapeptide-3 can enhance the functions in a variety of skin care and color cosmetic formulations.
    They are available in both water dispersible form (Corum 8804) and oil dispersible form (Corum 8814 / 8814CC).
