Dr. Pickart,
I am 45 and have been using Retin-A cream 0.05% nightly for about 3 months now. I love it, but also adore your Super CP Serum. Can they work in conjunction, for even more potent anti-aging results? In other words, do the 2 work well together? Retin-A at night and Super CP Serum during the day?
Your advice would be appreciated.

Yes I would like information on using the two together as well. I have GHK serum

Yes, use both products.

Skin Biology was set up to improve the look of skin.

The reason that we moved into cosmetic skin care was that women who were having difficulty with retinoic acid (Retin-A) or hydroxy acid tried other products and said that using either retinoic acid or hydroxy acid along with the Skin Rejuvenating Copper Peptides gave a much better skin response for them.
