I want to you Retin A or Tretinoid (I think this is the way it is spelled - in the family of Retin A - may be the generic form).

Can I do the following? 1) Wash my face with the Skin Biology face wash. 2) Apply some GHK cream on my face and a bit of Emu oil around my mouth - which has a tendency to become dry in my personal situation. Wait 30 minutes and then apply the Tretinoid/Retin A where I have brown spots? Or does the Retin A have to be applied by itself?

Dear Raine:

When using the more fragile copper-peptide: GHK-Copper we actually recommend that if clients are planning on using retinoic acid and hydroxy acid they should use it at the opposite end of the day.

Tretinoin and Retin-A are used at night, so what you can do is use your Super GHK-Copper Cream plus Emu Oil-S in the morning. But use your retinoic acid product by itself at night.

Best Wishes,
-Skin Biology

Thank you Skin Biology!
