"If you want a higher concentration of niacinamide, Paula's Choice 20% Niacinamide is something you can choose. It is going to be a little bit more pricey, and I am not sure that 20 percent is going to do a whole lot more for your skin than 10 percent."

"They have the 20% Niacinamide, another great example of every study into niacinamide shows that with a few exceptions where some people, a very niche subset of people could benefit from a higher dose, most people will get maximum results minimum side effects at around the 2 to 5% strength. So why do Paula's Choice have a 20% Niacinamide? For the tiny cohort of people that might actually be appropriate and beneficial, there's a whole host of people out there using it believing the stronger is better and actually suffering and experiencing a lot of side effects as a result. Not science backed, not appropriate for the mass market."
