Did nothing [SEP] This did nothing. It didn't hurt. It didn't help. It absorbs quickly and disappears as if it was never there. Maybe I'd see more of a difference if I wasn't already using a brightening essence, but even so it renders this pointless. I won't be repurchasing this.<br /><br />Minor gripe: the dropper is VERY cheap. I'm all for cutting costs where you can, but it's a little jarring at first.
