Concern

Oiliness & pores

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.

Combine with other concerns

Actives that work

Niacinamide

moderate evidence Typical: 2-5%

Appears to reduce oil output and supports the barrier. A trial found 2% niacinamide significantly lowered sebum excretion at 2 and 4 weeks.

Salicylic acid

moderate evidence Typical: 0.5-2%

Dissolves oil and dead cells inside pores, helping pores look clearer. Evidence is stronger for acne than for pore size specifically.

Retinoids

moderate evidence Typical: 0.1% adapalene or 0.25-0.5% retinol

Increase cell turnover so pores clog less, which supports clearer-looking pores over time. Strongest data is for acne.

What to buy

Routine

Morning

  1. Gel or foaming cleanser
  2. Niacinamide
  3. Oil-free SPF 30+

Oil control and pore changes take about 4-12 weeks to show.

Cautions. Over-cleansing and harsh scrubs can increase oil; keep moisturizing. See a dermatologist if breakouts are deep or painful.
