Yes, niacinamide is one of the more consistently recommended cosmetic actives for the appearance of pores, particularly for oily and combination skin where they tend to be most visible. It will not change the physical size of a pore, which is largely determined by genetics and skin type, but it is associated with a more refined-looking complexion with consistent use.
What niacinamide actually does for pore appearance
Pores look larger when they are congested, when the surrounding skin is uneven in texture, or when excess sebum makes them more prominent. Niacinamide reached dermatologist consensus for redness and dark spots in the JAAD 2025 Delphi study, a two-round expert review completed by 62 dermatologists across 43 centres, and its soothing reputation means the skin around pores tends to look calmer and more even with regular use.
It is worth being direct about what it cannot do. Niacinamide is a cosmetic active, not a structural treatment. What changes is how the skin looks and how congested the pores appear — and that is where it has a genuine, well-documented role.
Is it better than other options for pore appearance?
Retinol reached dermatologist consensus specifically for large pores in the same study and is associated with a more refined skin texture through its effect on cell turnover. Salicylic acid, being oil-soluble, works inside pores and is associated with a less congested appearance. Niacinamide sits alongside these rather than replacing them. It is gentler and suits a wider range of skin types, making it a practical supporting ingredient in a routine that might also include either of the above.
Who benefits most from niacinamide for this concern
Oily and combination skin tend to see the most visible difference, since enlarged pores in these types are often linked to excess sebum and congestion. For normal or dry skin where pore appearance is a concern, niacinamide is still useful, but retinol as the lead active may be the more targeted choice.
For skin that is also sensitive, niacinamide is often the most practical starting point because it gets meaningful results without the adjustment period retinol requires.
