Knowledge of Copper Peptide GHK CU in Skin Care
Blue copper peptide, also known as Copper Tripeptide-1/Copper peptide GHK Cu powder, is a ingredient that people who pay attention to skin anti-aging have all heard of. Today, let's take a deeper look at this component of copper peptide GHK powder and see how it achieves the effect of skin anti-aging and what its anti-aging effect is like? What is its anti-aging principle? Does it have any other uses?
1.What is Copper Tripeptide-1/GHK CU powder?
(1)Core definition:
1)The scientific name of the copper peptide GHK powder is glycyl-aminoacyllysine-copper (II) complex, abbreviated as GHK-Cu.
2)It is a complex formed by the tight binding of a tripeptide (glycine-histidine-lysine, that is, GHK) naturally existing in human blood with a divalent copper ion (Cu²⁺) through chelation.
This chelating structure endows it with a unique blue appearance (the color of copper ions) and special biological activity.
(2)Discovery and Source:
1)GHK was first isolated and identified from human plasma in 1973.
2)Research has found that the GHK content in young people is significantly higher than that in the elderly, suggesting that it is closely related to the youthful state and repair ability of tissues.
In the skin, copper peptide GHK-Cu is naturally present in body fluids such as plasma, saliva and urine, and participates in maintaining skin health.
(3)Chemical properties
1)Stability: The chelating effect of copper ions with GHK tripeptide makes it more stable than free copper ions or GHK peptides alone, reducing the risk of oxidative damage and maintaining its active form in the skin environment.
2)Bioavailability: Despite its relatively large molecular weight, studies have shown that GHK-Cu can effectively penetrate the stratum corneum and reach the dermis to exert its functions. Its transdermal absorption efficiency is a key point in the research of similar components.
2.The mechanism and core efficacy of Copper peptide GHK CU in skin care:
The mechanism of action of GHK-Cu is multi-target and multi-pathway, just like a "biological signal commander", promoting skin health and rejuvenation in a coordinated manner by regulating gene expression, activating key cellular processes and providing necessary copper ion nutrition.
(1).Outstanding skin repair and regeneration: (This is its most core and renowned function)
a.Promoting wound healing: GHK-Cu can significantly accelerate the healing process of various types of wounds, including surgical incisions, burns, ulcers, and wounds after laser/glycolic acid peels. It passes through:
1)Stimulate the migration, proliferation and differentiation of fibroblasts and keratinocytes.
2)Increase the expression of key growth factors such as epidermal growth factor (EGF) and transforming growth factor (TGF-β).
3)Promote angiogenesis and improve blood supply and nutrition at the wound site.
4)Regulate the activity of collagenase (MMP) and optimize the degradation and remodeling of extracellular matrix (ECM).
b.Repairing light damage: It has a powerful repairing effect on skin damage (photoaging) caused by ultraviolet (UV) rays and reverses the signs of photoaging.
c.Repair barrier function: Promote the synthesis of barrier-related substances such as ceramides, hyaluronic acid, and chondroitin sulfate, strengthen the skin's physical barrier and moisture retention capacity, and improve dryness, flaking, and sensitivity.
(2)Powerful anti-aging and firming enhancement
1)Stimulating the synthesis of collagen and elastin: GHK-Cu is a powerful promoter for the synthesis of collagen (type I, type III, type IV), elastin, glycosaminoglycans (such as hyaluronic acid), fibronectin, and laminin synthesis.This is the fundamental way to combat wrinkles, sagging, and enhance skin firmness and fullness.
2)Inhibition of matrix metalloproteinases (MMPs) : Factors such as ultraviolet rays can activate MMPs (such as MMP-1, MMP-2, MMP-3, MMP-9), which break down collagen and elastin like scissors. GHK-Cu can effectively down-regulate the expression and activity of MMPs, protect existing collagen and elastin from excessive degradation, and achieve "increasing income and reducing expenditure".
3)Improve skin texture and pores: By promoting ECM regeneration and epidermal renewal, it makes the skin surface smoother and more delicate, visually reducing enlarged pores caused by skin laxity and collagen loss.
(3)Powerful antioxidant and anti-inflammatory properties
1)Direct elimination of free radicals: GHK cu itself has antioxidant capacity, and copper ions are cofactors of important antioxidant enzymes (such as superoxide dismutase SOD). The GHK-Cu complex can synergistically eliminate harmful free radicals such as oxygen free radicals and hydroxyl free radicals, protecting cells from oxidative stress damage.
2)Anti-inflammatory effect: GHK-Cu can inhibit the expression of various pro-inflammatory factors (such as TNF-α, IL-6), reducing redness, swelling, irritation and inflammatory responses of the skin. This is very beneficial for soothing and calming acne, rosacea, eczema and sensitive skin.
(4)Brighten skin tone and improve pigmentation
1)Inhibiting tyrosinase activity: Research shows that GHK-Cu can inhibit the activity of tyrosinase, a key enzyme in melanin synthesis.
2)Reduce melanin transfer: It may interfere with the transfer of melanosomes to keratinocytes.
3)Promote healthy keratin renewal: Accelerate the shedding of old keratinocytes with excessive melanin.
4)Repairing light damage: It has an improving effect on ultraviolet-induced pigmentation (sunspots).
(5)Provide essential copper ion nutrition
Copper is a cofactor for many important enzymes, such as lysyl oxidase (LOX), cytochrome C oxidase, and SOD. These enzymes are involved in key physiological processes such as collagen/elastin cross-linking (maturation), cellular energy metabolism, and antioxidant defense. GHK-Cu provides essential copper elements for skin cells in a bioavailable form.
3.The core advantages of copper peptide GHK-Cu:
1)Multi-functional integration: Combining repair, anti-aging, anti-oxidation, anti-inflammation and brightening, it covers multiple core demands of skin care.
2)High biocompatibility: Naturally present in the human body, it is usually very gentle and has excellent tolerance, making it highly suitable for sensitive skin, rosacea skin, post-medical aesthetic repair, and long-term use by all skin types. Its irritation is far lower than that of retinol, high-concentration acids, etc.
3)The mechanism of action is scientifically in-depth: With a large number of in vitro, in vivo (animal) and human clinical studies supporting its efficacy, it is one of the most thoroughly studied peptide components.
4)Precise signal regulation: By regulating gene expression, it mobilizes the skin's own repair and regeneration capabilities, resulting in more natural and lasting effects.
5)High safety: At the prescribed concentration for cosmetics (usually 0.1%-2%), it has good safety.
4.Safe compatibility: Copper peptide GHK Cu powder can be well combined with the following ingredients:
a.Moisturizers such as hyaluronic acid and glycerin
b.Nicotinamide (Pay attention to the purity of nicotinamide and avoid containing nicotinic acid)
c.Asiaticoside, bisabolol, panthenol and other soothing and repairing ingredients
d.A variety of peptides (signal peptides, carrier peptides, etc
e.Mild antioxidants (such as vitamin E derivatives, ferulic acid, ergothioneine)
f.Lipids such as squalane and ceramide
