GHK-Cu

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper peptide complex found in human plasma, saliva, and urine. It has gained popularity in skincare, anti-aging, and hair restoration due to its regenerative and healing properties.

Discovered in the 1970s, GHK-Cu is widely studied for its role in tissue repair, collagen production, and skin rejuvenation.

How GHK-Cu Works

GHK-Cu functions by binding copper ions and delivering them to cells, which helps activate multiple biological processes:

• Stimulates collagen and elastin production
• Promotes wound healing and tissue repair
• Reduces inflammation
• Supports antioxidant activity
• Encourages hair follicle growth

It also influences gene expression linked to regeneration and anti-aging.

Key Benefits of GHK-Cu

1. Anti-Aging & Wrinkle Reduction

GHK-Cu helps firm the skin and reduce fine lines by boosting collagen synthesis.

2. Skin Repair & Healing

Widely used in dermatology for improving:

• Scars
• Sun damage
• Skin elasticity

3. Hair Growth Support

GHK-Cu is commonly included in hair serums to:

• Stimulate hair follicles

4. Anti-Inflammatory Effects

It helps calm irritated skin and may benefit conditions like acne or redness.

Common Uses of GHK-Cu

GHK-Cu is available in various forms:

• Topical creams and serums (most common)
• Injectable peptides (clinical/research use)
• Cosmetic formulations for anti-aging and hair care

GHK-Cu in Skincare

GHK-Cu is a key ingredient in many premium skincare products. It is often marketed as a “copper peptide serum” and is used to:

• Improve skin firmness
• Even out skin tone
