Query: Warning: This Product does not contain Hydroquinone

It appears that D&R produces two versions of skin bleach: one with and one without hydroquinone. The product I received does not contain hydroquinone. Unfortunately, hydroquinone is the only substance that I know of that is proven to work. None of the ingredients on this product are proven to do any skin lightening as far as I know. For that matter, the list of ingredients doesn't even include an "active ingredient".
