LOVE THIS FOR MY SENSITIVE SKIN
I have been using this product for a few months now and my skin is more even and more bright. It docent irritate my skin at all. LOVE IT!

This exfoliator should not be used every night no matter how strong your skin is. 2 times a week is enough or else you are over exfoliating.

(Tried Nov 2020) It's been a minute since I last used this product but I do remember that it took some time to find the best/ most efficient way to integrate this into my routine. Since it is a powder, another serum/moisturizer is required to dissolve it. Despite diluting it with another product, I felt that I could not get the irritation/stinging to be less potent. So it definitely became a matter of using less than half of the standard amount. At that point it become more bearable to use and I did notice the effects. I wouldn't say it's the most convenient product to use for brightening compared to others.
