Is Kojic Acid A Safe And Effective Skin-Lightener ...
And Kojic Acid is more effective than mulberry extract and Arbutin (a natural form of hydroquinone). I couldn’t find any studies comparing Kojic Acid to other skin-lighteners, like Azelaic acid. But given the irritating potential of Kojic Acid, I’d still try gentler skin-lighteners like Arbutin and Azelaic acid first.
