Derma Factory Niacinamide 20% Serum

What is this product?

A minimal 30ml serum built on just ten ingredients, rose flower water first and niacinamide second at a disclosed 20 percent, the highest concentration commonly sold for this active. That figure is not a single mention: an independent Korean-labeled listing of the same product name prints the same 20 percent, though this record did not confirm whether every size sold under this name shares one formula. No fragrance, no oil and no ester of any kind appear in the list, and no pH, no clinical test and no manufacturer name were found on the surfaces checked for this record. Niacinamide's own literature is best established between 2 and 10 percent, so 20 percent is a strong number to buy on but not one this record can call tested at that level.

What makes it different?

The single defining fact here is concentration: 20 percent niacinamide is well above the 2 to 10 percent range most commonly cited in the ingredient's own efficacy literature, and unusually for a K-beauty label, the number sits in the product's own name and URL rather than being buried in a spec sheet. It is also cross-confirmed on an independently labeled Korean listing rather than resting on one printed mention. The formula around it is stripped down to ten ingredients with no fragrance, oil or ester, which is the minimalist, single-active positioning this brand builds its whole catalog on rather than something specific to this product alone.

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.

Did the ad claims hold up?

We checked 3 lines this product advertises against the ingredient list and public documents. 2 of them hold up. The rest are only partly right or have nothing behind them.

Each line is quoted as the brand published it, and each one was read on its own against the ingredient list and the documents the brand publishes.
