I was looking at the product ingredient list, and noticed that the SS Cream called out copper tripe pride (GHK-copper) and SS Solution calls out copper-peptides(hydrolyzed soy protein & copper chloride).

Can you explain to me the different in the two copper ingredients?

Dear Wish:

Yes, Skin Signals Cream is a mix of the 2nd generation copper-peptides and 1st generation GHK-Copper (copper tripeptide-1 GHK-Cu), whereas Skin Signals Solution has only the 2nd generation copper-peptides (which is a mix of hydrolyzed soy protein and copper chloride).

Both products were specifically developed to give a contoured, lifted look and tighter appearance to the skin and highlight the addition of enzymatically hydrolyzed collagen and elastin peptides.

Which Generation of Copper Peptides Is Stronger/Better?
"Stronger" might not be the best description - "Better suited for certain skin rejuvenation tasks" might be a more appropriate phrase. The type of rejuvenation needed and the client's skin type and goals will dictate which is better for that particular individual. Remember, "stronger" doesn't necessarily mean better / Many feel the best of both worlds would be to use a product that employs the use of both 1st and 2nd generation copper peptides, such as Skin Signals Cream.
