What is GHK-Cu?
- GHK-Cu is a naturally occurring copper peptide studied for its role in cell repair, tissue regeneration, and skin health signaling. It consists of the tripeptide GHK bound to copper ions, a combination that plays an important part in cellular communication and healing processes.
- Because of these properties, GHK-Cu is widely researched in areas related to skin rejuvenation, connective tissue strength, hair follicle health, and anti-aging science.
What Studies Have Found
Encourages Collagen & Elastin Production
Supports pathways involved in maintaining skin firmness, elasticity, and structural strength.
Provides Antioxidant Support
Helps protect cells from oxidative stress linked to aging and environmental damage.
Supports Hair & Follicle Health
For its potential role in maintaining healthy hair follicles and scalp tissue.
Supports Skin Barrier Function
Suggests it may help maintain the skin’s protective barrier and overall integrity.
Potential Side Effects
- Skin Irritation or Redness – Mild irritation, redness, or itching may occur at the application site in some research settings.
- Temporary Burning or Tingling Sensation - A brief warming or tingling feeling has been reported during early exposure.
- Allergic Sensitivity (Rare) – Individuals sensitive to copper or peptide compounds may experience localized reactions.
- Inflammatory Response – Short-term inflammation may occur as part of active tissue repair signaling.
- Discoloration at Application Site – In rare cases, copper-related pigmentation changes have been observed.
- Headache or Mild Fatigue – Temporary systemic responses may occur as the body adapts to cellular signaling changes.
