I got to try this. I loved it so much that I used up my 2nd bottle of cosrx niacinamide 15 serum, and I’m genuinely impressed. With a high concentration of 15% niacinamide, this serum is made to target acne, control excess sebum, and even out skin tone.
The packaging is good and hygienic, with a dropper that dispenses just the right amount.
The texture is lightweight and absorbs quickly without leaving a sticky residue, which makes it easy to layer with other products. I noticed a visible reduction in the size and redness of breakouts within the first week. Over time, my skin looked more balanced and less oily, especially around my T-zone.
By the way, because of the high niacinamide content, it might be a bit strong for those with sensitive skin. I started using it every other night to build tolerance, and that worked well for me. Do try it
