Invisible pores

Pores are normal! You can’t really shrink them or make them disappear. The best thing to do is make sure you’re thoroughly cleansing and using an oil control product such as bha and niacinamide

I think some sunscreens have that sort of finish/effect - James Welsh on YouTube always looks poreless and that's how he achieves it. I personally haven't explored that territory but look him up - perhaps you'll find your answer 👌
