Derma Factory Niacinamide Serum

Looking at the photo, it looks more like a medicine bottle than a cosmetic bottle haha

I became interested in the ingredient niacinamide, so while looking it up, I found an ampoule containing a high concentration of 20% and purchased it.

They say you need to use it consistently for about a month to see results.

I heard it has whitening properties that brighten the skin tone, so I plan to use it consistently.

Now, when buying cosmetics, I check the ingredients the most.
