(This Week's Self-Purchased) Derma Factory Niacinamide 20% Serum 30ml

Derma Factory Niacinamide 20% Serum 30ml.

I purchased this directly from an online shopping mall after receiving recommendations that niacinamide is good for controlling oiliness. My skin has turned oily, so managing oil was difficult. This product contains a high concentration of 20% niacinamide. I heard that the B3 component helps with brightening, sebum control, pore management, and oil control. The texture feels like applying glycerin; it absorbs quickly and isn't sticky. I was advised to pump only twice because applying too much leaves a white, powder-like residue. I definitely liked that applying it at night before bed prevented oil from rising to the surface in the morning. It effectively controls oil, making it the best for oily skin.
