I received a free sample of the new Skin Signals.
I'm currently using on my entire face, including under my eyes, Super Cop 2X. Isn't Skin Signals significantly weaker than Super Cop 2X? I do not want to downgrade my potency just yet as I haven't achieved all the results desired from a stronger CP. I've been using your products since Dec. 08 with promising results. Scars, pores & wrinkles are fading/diminishing. What's the shelf life of the Skin Signals if I hold off on using it?

Dear Junko:

Skin Signals is milder than Super Cop 2X Extra Strength (our strongest product as far as concentration of copper-peptides). But stronger doesn't necessarily mean better.

Clients using Super Cop 2X may still want to sample/use Skin Signals especially for certain areas as it might be particularly helpful for skin tightening.

Skin Signals, as is the case with the other copper-peptides, does not have a stated shelf-life or expiration date. Copper-peptides seem to keep fairly well as long as they are kept in a cool place.

You can always refrigerate the product if you plan on using it later on.

Best Wishes,
