Molecules (Basel, Switzerland) · 2025

Researchers reviewed the challenges of delivering a beneficial skin compound called GHK-Cu, which can help reduce wrinkles and improve skin elasticity. They found that using liposomes to encapsulate GHK-Cu might enhance its ability to penetrate the skin barrier, but noted that this area has not been extensively studied.

• GHK-Cu is a naturally occurring compound that can improve skin appearance but struggles to penetrate the skin effectively.
• Liposomes may enhance the delivery of GHK-Cu through the skin barrier.
• There is a lack of research on the effectiveness of liposomes in transporting GHK-Cu, highlighting a gap in current scientific knowledge.

Redox biology · 2024

Researchers studied the effects of a natural peptide called GHK-Cu on silicosis, a lung disease caused by silica exposure. They found that GHK-Cu reduced lung inflammation and fibrosis in mice, suggesting it may help manage the condition by targeting oxidative stress in immune cells.

• Researchers observed that GHK-Cu reduced lung inflammation and fibrosis in a mouse model of silicosis.
• The study identified that GHK-Cu binds to a specific protein, peroxiredoxin 6, which plays a role in reducing oxidative stress.
• GHK-Cu showed no significant systemic toxicity, indicating it may be a safe option for further research in treating silicosis.

Journal of cachexia, sarcopenia and muscle · 2023

Researchers studied the role of a natural peptide called glycyl-l-histidyl-l-lysine (GHK) in muscle dysfunction related to chronic obstructive pulmonary disease (COPD). They found that GHK levels were lower in COPD patients compared to healthy individuals, and that GHK-Cu could improve muscle health in lab models exposed to harmful substances.

• GHK levels were significantly lower in COPD patients compared to healthy controls.
• GHK levels were linked to muscle mass and inflammation in COPD patients.
• GHK-Cu treatment improved muscle function in experimental models exposed to cigarette smoke.

Aging pathobiology and therapeutics · 2020

Researchers studied GHK, a natural peptide that decreases in the body with age, and found that it has properties that may promote skin healing and reduce inflammation. Additionally, early findings suggest it could help improve cognitive function in aging mice. This study highlights the potential of GHK as a focus for future aging research.

• Researchers observed that GHK levels decline from an average of 200 ng/ml at age 20 to 80 ng/ml by age 60.
• The peptide and its copper complex, GHK-Cu, demonstrated anti-inflammatory and tissue remodeling effects.
• Preliminary data suggest GHK may help reverse cognitive decline in aging mice by targeting specific biological pathways.
