Classified by the FDA as a wound-healing agent, LYCD (also called Biodyne), is a skin respiratory factor that helps skin cells to promote the healing process through the uptake of oxygen.

Patented by Dr.Sperti in 1939, he named it Biodyne because it stimulates healthy cell growth. The word Biodyne comes from the Greek words bios (life) and dyne (force).

The Theory of Cell Injury  

When cells experience injury or destruction, some will produce hormones which stimulate cellular multiplication so that the tissues heal. Dr Sperti's group, who discovered Biodyne, found that they were able to isolate three distinct substances from the dead tissue.  

Those that accelerate the cellular metabolism of sugar
Those that stimulate growth and reproduction
Those that stimulate cell reproduction.  

Collectively, these substances were named Biodynes.

Further research at the University of Cininnati demonstrated that biodynes could be extracted from heated yeast cells. This type of biodyne is called Live Yeast Cell Derivative (LYCD) and contains nutrients such as proteins, amino acids, minerals, carbohydrates, nucleic acid and other gene products. The active ingredient has even been isolated as a protein fraction containing a mixture of several peptides one of which is a peptide fraction that stimulates wound healing. Biodyne is known to be biologically active on skin cells. Cinical studies from the Cincinnati Burn Unit and Oregon University School of Medicine show that Biodyne speeds wound healing in burns and post surgically.

Biodynes (LYCD) are also known as Skin Respiratory Factor and Tissue Respiratory Factor.

Can LYCD Relieve Puffy Eyes?

Though not clinically proven, anecdotal evidence suggests that LYCD can help to relieve puffy bags under the eyes. And some individuals report a reduction wrinkles. LYCD is found in the version of Preparation H sold in Canada. It was removed from the US formulation several years ago, where it was replaced by phenylephrine, an ingredient that can be highly irritating to the eye area.
