Hi,
How long does it take for cp serum to work on the skin before it's washed off? I need to know because I want to try using it in the morning for awhile before I put on my sunscreen that contains 6% zinc. I have been using cp serum at night but I found out I shoud be putting it on after my retinol (Green Cream) instead of before and feel like I'm diluting the retinol with that water and cps together. So what should I do?

Thank you for the help Smiler

You should give CP Serum at least 30 minutes on your skin.

hi Dr. Pickart:
This is an interesting question and one I wanted to ask myself. If you apply CP, and leave it on for 30 minutes, do you receive all the benefit, 80% of the benefit, 40% of the benefit, etc?

I also use a zinc sunscreen and did not know that was a problem until recently, although I have been using CP for a year now. I wonder if I am getting all the benefit from my CP (for example, sometimes I apply supercop all over my face and never get ANY uglies but maybe the zinc sunscreen is inactivating the CP??)

I appreciate your help as I am trying to maximize the benefit to my skin. Thanks :-)

If your pores are not enlarging and your skin looks good, then continue what you are doing.

There are no good studies of copper-zinc combinations.
