Dear Dr, Pickart and Skin Biology,

I would like to know if I can use Hydroxypinacolone Retinoate and GHK-Cu in the same evening.

Look forward to your advice.

Dear carrot:

Thank you for posting your question!

Dr. Pickart said "Long ago, women using retinoic acid found that also using GHK-Cu had better results. The two should just be tried cautiously."

Typically we suggest for clients wanting to use retinoic acid and copper peptides use the two products at opposite ends of the day.

Others like to alternate (e.g. use Retinoic Acid product one day / use GHK-Cu product the next night)...

Best Wishes,
-Skin Biology
