Hi, I have been using Super CP Serum along with Retin-A 0.5% for about 8 months with no problems. Do you think I should now move up to the Super Cop as well as Retin-A or just stick with the Super CP Serum. Thanks for your help.

Dear Fukeliu:
You are a good candidate to move up to the stronger Super Cop 2X cream.
