Helps fade dark spots
I had to stop using the Eucerin Dual Serum as it kept giving me pimples. But, after experiencing first hand how effective thiamidol is and how it fades dark spots, I continued to use the spot corrector on its own. I use as part of my evening routine. The spots dont dissapear, but it does help fade them a little. Something, is better than nothing.
