I used half the bottle so far, but I dont really see a drastic change or whiting in my skin. It works, but I really hate how it is super sticky. 

My skin (combination type) can absorb fast this serum but at the beginning of using, I feel a little bit itchy 

Oxidizes very quickly. Recommend to keep in fridge. 

It's a little bit too sticky to my liking. I find the serum quite harsh, as it makes my face red and itchy after application. I only use this once in a while during my night skincare routine.

I've only been using this for a couple of weeks but I think it's been helping with brightening my skin and lightening scars.
