Is liquid hydroquinone just as effective as a cream form or is it better?

I've heard liquid hydroquinone is more effective than a cream form because it penetrates better. I know the Obagi C Rx line has a liquid form of hydroquinone were as their NuDerm line is in a cream form, both 4%. The Obagi C Rx does have 10% vitamin C mixed with it. Do you recommend liquid over cream form?
