On paper this serum sounds perfect for my skin and for the environment. In reality my skin hated it and broke out with lots of white heads, especially around my chin area. It's the same reaction I had with other Niacinamide products and I believe my skin just doesn't like products where Niacinamide is the main ingredient (or ingredients that mimic its effects). This serum also smells like and contains a lot of alcohol, naturally derived but still alcohol. That's an instant no for me.
