No. They can be cleared, and the skin around them can be improved so they're much less visible. That distinction is the whole difference between products that work and products that overpromise.

Two to three times a week to start. Daily BHA is fine for some oily skin but it's not where to begin, and over-exfoliating makes texture worse, not better.

They remove the visible tip and leave the rest, and repeated use stretches the opening. A BHA and regular oil cleansing achieve more with no downside.

Niacinamide for oil control, and it's easier to tolerate. Retinal or retinol for the structural improvement. Using both is the standard approach — start with niacinamide and add the retinoid slowly.

Heat increases sebum production, and sunscreen plus sweat needs proper removal. Add an oil cleanse before your usual face wash before you change anything else.
