Oiliness and visible pores are largely driven by oil production and genetics; pore size can't be permanently shrunk. Niacinamide and salicylic acid can make pores look smaller and shine look calmer.
Appears to reduce oil output and supports the barrier. A trial found 2% niacinamide significantly lowered sebum excretion at 2 and 4 weeks.
Dissolves oil and dead cells inside pores, helping pores look clearer. Evidence is stronger for acne than for pore size specifically.
Increase cell turnover so pores clog less, which supports clearer-looking pores over time. Strongest data is for acne.
