一开始有点刺痛在皮肤上，但是连续用了几天后就习惯了，而且看得到效果

I just started using this and my first impressions are that it is just ok. It actually stings a tiny bit and the texture is hydrating but also slightly oily for me. Leaves skin slightly sticky too. But it hasn't given me bad reactions so I will continue to use it and see if it does any brightening! 

This essence is very moisturizing and brightening so far I can see a difference.

very impressed, makes my skin very soft.

I use this every day and night. My hyperpigmentation is going away and well as my acne scars. I'm not sure if it is 100% this product or my routine as a whole. I do enjoy using this essence though. May repurchase if I don't see anything else I wanna try for an essence.
