GHK-CU (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper-binding peptide known for its regenerative and restorative effects.

It plays a role in wound healing, tissue remodeling, and skin regeneration. GHK-CU has also been studied for its ability to stimulate collagen

synthesis, promote hair growth, and provide anti-inflammatory benefits.

• Skin Regeneration: Stimulates collagen and elastin production for improved skin tone and elasticity.

• Hair Growth Support: Promotes follicle health and hair density.

• Wound Healing: Accelerates repair of damaged tissue.

• Anti-Inflammatory: Reduces oxidative stress and inflammation.

• Shown to improve wound healing and reduce scar formation.

• Demonstrated skin rejuvenation effects in cosmetic and dermatological studies.

• Preclinical and clinical data suggest benefits in hair regrowth.

• Generally well tolerated in nasal spray forms.

• Mild side effects: skin irritation, redness, or itching at application site.

• Long-term systemic safety data are limited.

• Research protocols vary depending on application:

– Topical: creams or serums for skin and hair.

– Injectable: microinjections or mesotherapy in dermatological settings.

• Typical concentrations range from 1–2% in topical formulations; injectable dosing varies in research contexts.
