I was hesitating between 4&5 stars. It did the job of maintaining my breakouts in check ( combination skin), but I coul skull get some occasional pimples and it was maybe shortening the heal up, but didn’t make them stop miraculously. I had some niacinamide serums from other brands that did wonder on stopping start of inflammation over night, this didn’t do it as powerfully. But still it’s decent niacunamide serum. Another slight negative - I feel that it finished too quickly, usually I have at least a month of this serum quantity, but here it run out in 2,5 weeks.
I have sensitive, mixed skin and this product does wonders. I could see the difference already the morning after using it, skin is smoother and more plump
I really see a difference in a short time. Always had those pimples on my chin and after using it for a few days, they got less and aren’t red anymore.
