A 10% niacinamide (vitamin B3) serum applied morning and night. It regulates sebum production, minimizes enlarged pores, fades post-acne hyperpigmentation, and strengthens the skin barrier. One of the most well-researched actives for oily or acne-prone skin — and it layers safely with almost everything.

Pores visibly smaller after 6 weeks. My skin looks like it's been filtered IRL.

Oiliness under control by week 3. Stacks perfectly with my retinol.
