(Advertising ❌) It is a content produced by studying papers and research materials for a long time.
The paper adopted in this content did not test the niacinamide content (%) for each skin problem, but was first tested on subjects suffering from each dermatitis by specifying the content (safety content) in the study stage.
Please refer to the contents in the paper and I think you can get help if you use it consistently with a similar content or slightly higher or lower content. ^^
I hope this video will be helpful for those who have a lot of skin concerns and are interested in niacinamide, and I share information on the exposed products as below.
The paper shows that 5% niacinamide helps whitening, and if you want to try the exact 5% content, I recommend Advanced Clinics, a 5% serum of niacinamide. (Sales of iHub)
