Fei review for 2% Alpha Arbutin

It has a slimy viscous consistency that feels exactly like snail mucin for some reason and I absolutely love it. After initial application, it does feel hydrating but once it fully sink into the skin, it no longer feels hydrating. In some cases, it might be a pro cuz that means it'll leave no sticky or tacky finish. But to me, I need to layer on another hydrating serum to give my skin a boost of hydration or else my skin will feel dry and tight throughout the day. In terms of efficacy, I'm pretty impressed by the results. So far, I've noticed that my post acne marks have faded much faster than usual even when I'm using my other brightening serum. This by far might be the most effective brightening product that I've tried to fade hyperpigmentation. I'm not exaggerating but this might has a chance to be my next Holy Grail.
