Serum trị đốm đen

The texture sinks in fast without that sticky feeling, and my skin tone looks more even around my cheeks after three weeks of nightly use. The niacinamide definitely pulls its weight here, even though I was skeptical about the prebiotic angle at first.

My post-acne marks on my chin have noticeably calmed down since I started using this nightly, and the prebiotic formula doesn't irritate my sensitive skin at all. It sinks in fast with no greasy residue, which is exactly what I wanted before moisturizer.

Three weeks in and the niacinamide really is doing its job—my post-acne marks have visibly lightened, and it layers perfectly under moisturizer without any pilling. The texture sinks in fast, which makes it easy to stick with every night.
