Sensitive skin is characterized by symptoms of discomfort when exposed to environmental factors. Peptides are used in cosmetics for sensitive skin and stand out as active ingredients for their ability to interact with skin cells by multiple mechanisms, high potency at a low dosage and the ability to penetrate the stratum corneum. For example, palmitoyl tetrapeptide-7 decreases IL-6 secretion, reduces inflammation after UVB exposure and stimulates laminin IV and V as well as collagen VII production.
Palmitoyl tetrapeptide-7 is a fragment of immunoglobulin IgG. Tetrapeptide-7 can significantly eliminate skin inflammation, reduce skin wrinkles and restore skin activity, by acting on keratinocytes and fibroblasts to reduce the release of IL-6.
Copper tripeptide-1 in cosmetics is a complex of tripeptide and copper. Copper tripeptide-1 can activate skin regeneration function, dilute scars, reduce pigmentation, improve skin elasticity and brightness, and have a good effect on hormone face repair.
It is an anti-wrinkle and repair combination product, that can significantly reduce the level of inflammatory factors, reduce the deepening of skin wrinkles caused by inflammation, and promote collagen synthesis, reduce wrinkles, and make the skin compact and young.
Avena sativa oat kernel extract is an anti-sensitive and deep anti-wrinkle combination formula. Meanwhile, avena sativa kernel extract can effectively reduce inflammatory factors, remove deep wrinkles and restore smooth and youthful skin with oat kernel extract skin benefits.
Myristoyl hexapeptide-5 is a broad-spectrum antimicrobial peptide that has a good killing effect on propionibacterium acnes. The product can penetrate the dermis to increase collagen, rebuilds from the inside out, and reverses the skin aging process, also inhibits the growth of propionibacterium acnes to reduce acne inflammation.
What's the role of peptides in our daily skincare?
"Peptides are strings of amino acids, which are the building blocks that make up proteins in our body, including collagen in the skin, without these proteins, we will see wrinkles, brittle nails and dry hair that’s prone to breakage." Dr. Whitney Bowe said. Although there are thousands of peptides in the world, but they play a different roles in skincare products.
For example, carrier peptides deliver trace minerals to the skin to boost collagen, while enzyme inhibitor peptides work to slow down the skin’s natural breakdown of collagen. Signal peptides send messages to different parts of the skin to promote collagen, elastin and other proteins; and neurotransmitter peptides, touted as “Botox-like,” block the release of chemicals that cause the muscle contraction of expression lines, thus smoothing wrinkles.
