It looks like every brand in Korea includes niacinamide in their creams. I even found it listed in a cream that is not specifically marketed for anti-aging (Missha). It is interesting that Missha also offers anti-aging creams with niacinamide that are twice as expensive. Is there any real difference between different creams containing niacinamide or do they all offer the same benefits? How can I know which product is better? Does price matter? Is 20 000 won (20 dollars) for 50 ml too cheap or too expensive? Are eye creams different and is it necessary to buy a separate cream just to use around my eyes or I can just use any niacinamide cream there? I am also worried because I am already very pale so will niacinamide make my skin even whiter?
Some of the creams contain ethanol, isn't that a problem? Also, my skin is acne prone, is it safe to use niacinamide? What other ingredients should I be watching for? I wanted to buy a retinol cream because you said in your podcast that it was originally developed as an acne treatment but I could find only one such cream and it was sold out, haha.
