I know higher concentrations of hydroquinone are Rx only but I've heard 2% can still be bought over the counter. Is this still true? I've seen some stuff that can be bought online, but where can I get products that contain Hydroquinone in stores? Stores & pharmacies like Rite aid, walgreens, CVS, target, vons, etc. don't seem to carry anything like this? What are OTC products that can be used for PIH (preferably w/ hydroquinone)?
