GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper)

GHK-Cu is a naturally occurring copper peptide first discovered in human blood plasma in the 1970s. It plays a key role in a wide range of biological processes, including wound healing, tissue repair, and the regulation of collagen synthesis.

In dermatological research, GHK-Cu is recognized for its ability to stimulate the production of Collagen Type I and III, elastin, and glycosaminoglycans. It also exhibits antioxidant properties and supports the skin's natural renewal cycle.

After the age of 30, the body's natural GHK-Cu levels decline significantly — directly paralleling the visible signs of skin aging, including loss of firmness and the appearance of fine lines.

Multi-Molecular Hyaluronic Acid

Hyaluronic acid is one of the skin's primary moisture-binding molecules. The problem with most products: they contain only a single molecular weight. Blue Elixir Cream uses three molecular sizes that penetrate different skin depths, providing comprehensive hydration from the surface down.

Ceramide Complex

Ceramides are natural lipids that form and reinforce the skin barrier. They prevent transepidermal water loss and strengthen the skin's ability to defend itself against environmental stressors — keeping moisture in and irritants out.

Research & Sources

The efficacy of GHK-Cu is supported by peer-reviewed clinical research. Key studies are published in journals including the Journal of Aging Research and are indexed on PubMed. Contact us at info@sonahcare.com if you would like to receive specific study references.
