I started using kojic acid because it removes yellow dullness. I'm currently using a variety of lotions, but I remember that when I first used this, my skin texture improved and it became brighter. I also use Albion and Décolleté as pre-lotions, and they work well together. Also, as I previously commented about the scent below, I find this scent better than the AQ whitening lotion. So, I think I'll stick with kojic acid and continue using it. I'm also raising my rating by one. However, I'm deducting a star because I find the scent bothersome. I wish it was a little milder.
