The best vitamin c serum with high concentration of vitamin C. It didn't irritate my skin at all and the scent is barely discernible. I store it in the fridge to slow down oxidization.
I like the lightweight texture and it doesnt feel heavy on my skin. It's good serum, havent really noticed a huge deference in my face but i think I just need to use it longer to see a difference.
Still too early to give a good opinion about how effective it is, but when I do apply it, it does sting a bit (which I think should mean it works and is therefore a good thing). After applying it, my face feels tighter and smoother.
