I was wondering the percentage of retinol in your retinol/squalane. I've experienced great results when using it analagously with copper peptides.

Dear Roke:

See the thread at:

I don't think we disclose the exact percentage, but Dr. Pickart mentions: "It is as high as we can go without skin irritation."

Perhaps he will answer with further information.

Then I'm guessing between 0.2 to 0.3 %.

That's good enough for me, thanks.
