GHK-Cu
Copper peptide | Skin regeneration & anti-aging compound
Overview
What is GHK-Cu?
GHK-Cu is a naturally occurring copper tripeptide found in human plasma, saliva and urine. Its plasma levels decline from about 200 ng/ml at age 20 to about 80 ng/ml by age 60. Research shows it influences 31.2% of human genes and promotes wound healing, collagen synthesis and anti-aging effects. Note: injectable GHK-Cu is not FDA-approved; most clinical evidence comes from topical studies and animal models.
Key benefits
Increased collagen production, better skin elasticity, reduction of fine lines and wrinkles, accelerated wound healing, hair growth stimulation and convenient daily application.
Mechanism of action
Topical GHK-Cu penetrates the skin layers to deliver copper directly to target tissues. It activates fibroblasts, stimulates collagen and elastin synthesis, promotes angiogenesis and modulates inflammatory responses for optimal skin regeneration.
Quick start guide
What to expect
- Week 1-2: better skin texture and hydration.
- Week 3-4: reduction of fine lines and smoother skin.
- Week 6-8: greater firmness and skin elasticity.
- Week 8-12: visible improvement in skin tone and clarity.
- Hair growth: first results in 6-12 weeks.
- Most effective for: anti-aging, skin regeneration and hair growth.
Side effects & safety
- Do a patch test on a small area of skin before first use to check sensitivity.
- May cause mild skin irritation at first (usually resolves).
- Always use sunscreen, as copper peptides can increase photosensitivity.
- Avoid contact with the eyes and mucous membranes.
- Stop use if intense irritation or an allergic reaction appears.
- Allergic reaction: rash, itching or swelling.
- Intense, persistent irritation, redness or burning at the application area.
- Appearance of blisters or skin peeling.
- Worsening of any existing skin condition.
- If you are pregnant or breastfeeding, consult before using it.
