I would estimate it to be 0.01%

Why do you think so?

You can call it a trained intuition from reviewing a lot of formulas. There is no way to know for sure unless the manufacturer confirms it. 0.01% is the minimal effective concentration for retinol, and given how this product is marketed (no warning on intensity for example), I'd assume that this is what they went for.
