COSRX The Niacinamide 15 Serum 20mL

I have used this product for a few weeks now, I can notice a difference in my skin, my pores look smaller, my skin looks brighter, it has controlled the oiliness for sure not causing new breakouts. I used The Minimalist Niacinamide 0.5 and noticed some difference, but my face was still oily. Then, I decided to go up to Anua Niacinamide serum 10 but it was leaving my skin sticky and started getting some bumps in my skin. I was a hesitant to go up to 15 grade but it has not irritated my skin so far and it looks like it is definitely the grade I need. I will definitely re purchase this product.
