SK-II - ully review for Genoptics Spot Essence

I’m not sure about the “removing black spots” claims because I compared with its sister, genoptics aura essence and I think the sister more effective to reduce the apperance of dark spots. I’ve spent 1 bottle (30 ml) and I haven’t got my expected result. Maybe I need to be more patient??? I don’t know but I’ve repurchased my second bottle. Wish me luck
