It's moisturizing but I didn't notice anything different with my skin. It didn't really whiten anything. I have tried the LI Effector one and that one works much better.
At first I did not notice its effect but right after stop using, I can feel that my skin seems not to be as bright as before. It did take time to see the effect
Light, Have a nice smell. I didn't see a huge change in completion , perhaps slightly brightening. Might repurchase a different ampule.
