Dear Dr. Pickart,

I was wondering - I have read about different peptides increasing different types of collagen - like type I, II, III etc.

I was wondering - do copper peptides only increase type III collagen and if so; would you recommend using copper peptides with other types of peptides, to get the very best result for skin?

your advice would be very much appreciated,

thankyou,

Eve

Our mixed copper peptides (from soy protein) increase collagen 3, which is found in young people's skin.

GHK-Cu increases collagen 1.

Skin Signals uses copper complexed to our mixed peptides from soy protein plus peptides from collagen and elastin.
