I occasionally use Retin-A (about 4-6months of the year. I give my skin a break from all acids several months a year).

I want to use my CP Serum with my Retin-A. On your site, it says use before applying Retin-A. Do I need to wait for a while before applying Retin-A?

Thanks.

Dear kittenkat:

No wait time needed. You'll find other helpful tips at the links below:
