Introduction to Copper Peptides
GHK-Cu Powder was first isolated from human serum by Dr. Loren Pickart in 1973. They are composed of a tripeptide molecule consisting of three amino acids (glycine-histidine-lysine) complexed with a copper ion. Copper peptides appear in solid or solution form in shades ranging from deep blue to light blue, hence the name "copper peptides." Due to their stability and antioxidant properties, copper peptides are widely used in various fields such as anti-aging, promoting wound healing, and improving skin texture, making them a dark horse in peptide-based beauty products.
Biological Activities
Copper peptides naturally exist in the human body and play a role in various biological processes, including wound healing, skin repair, and reducing inflammation. Copper peptides exhibit several biological activities:
◆Antioxidant Action: GHK-Cu Powder can neutralize free radicals, protecting cells from oxidative damage.
◆Promotion of Collagen Synthesis: Collagen is a crucial component for maintaining skin elasticity and firmness. Copper peptides stimulate collagen synthesis, contributing to improved skin texture.
◆Enhanced Cell Activity: Copper peptides promote cell growth and proliferation, speeding up wound healing.
Additionally, copper peptides can be used topically or taken orally. When applied topically, they can be added to cosmetics such as creams, eye creams, serums, etc., to provide moisturizing, antioxidant, and skin-tightening effects. When taken orally, copper peptides can serve as supplements, promoting collagen synthesis to maintain skin elasticity and firmness, thus improving skin quality.
As an endogenous active peptide ingredient, copper peptides have garnered significant attention and are often referred to as "soft gold" due to their high value, with a price per kilogram comparable to that of gold.
Application Examples
Examples of copper peptide essence applications:
NIOD Copper Amino Isolate Serum (CAIS): A water-based serum containing 1% tripeptide-1 and 1% copper peptides. It is refreshing and non-greasy.
The Ordinary "Buffet" + Copper Peptides 1%: In addition to 1% copper peptides, this product contains various neurotransmitter peptide inhibitors that effectively tighten the skin and reduce wrinkles.
When using copper peptides, consider the following:
◆Concentration: Pay attention to the concentration of copper peptides. Excessively high concentrations may cause irritation or adverse reactions. It is advisable to use copper peptide products with appropriate concentrations, typically ranging from 0.1% to 1% copper peptide solutions.
◆Skin Sensitivity: For individuals with sensitive or easily irritated skin, perform a patch test before using copper peptides to ensure they do not cause allergies or irritation.
◆Usage Sequence: When using copper peptide products, apply them after cleansing and toning to prevent adverse pH conditions or interactions with other substances from affecting the active structure of copper peptides.
◆Avoid Simultaneous Use with Other Anti-Aging Ingredients: Copper peptides have specific usage requirements, and products containing EDTA, for example, can cause copper ions to be released, rendering them ineffective. Other antioxidants/whitening products can also interact with copper peptides, causing both to lose effectiveness. Therefore, when using copper peptide products, avoid using other multifunctional skincare products and simplify your skincare routine.
◆Storage: Store copper peptide products in a cool, dry place, away from direct sunlight, high temperatures, and humidity.
◆Expiry Date: Be mindful of the expiry date when using copper peptide products, as expired products may lead to irritation or adverse reactions.
In summary, when using copper peptide products, it is essential to consider their concentration, skin sensitivity, usage sequence, storage, and expiry date to avoid adverse reactions and protect skin health.
