Even when I was sensitive enough to sting whatever I applied, I could apply this without any irritation. It is moist even though it soaks in without oil.

I took it at a discount, for a trial. I have been using it for a month now, I have not noticed any visible changes in skin color and tone. Nice smell, quickly absorbed, I put a nourishing cream on top. I think the serum will last for 3-4 months, I will continue to use it, then I will see what the effect will be. PS I have been using the effect 0 for 2.5 months already.

The irritation is relatively large, so you must use a small amount of niacinamide skin care products for the first time, and increase the dosage after the tolerance is established. Lesson! lesson! The chin and both sides of the nose are peeled off, leaving black marks. I started to use the second bottle and I haven't seen any obvious changes.
