The question

Toners cannot permanently shrink pores, but a leave-on BHA may help reduce clogged-looking pores and shine for some people. Since your skin is sensitive, start with just one exfoliant slowly rather than combining the COSRX options.
The photo shows visible pores around the nose and inner cheeks, with some shine. That is common, and pore size is partly natural. Salicylic acid (BHA) has limited evidence for improving clogged-looking pores and rough texture, but it can also irritate sensitive skin.
Use one product on a small area first. If your skin tolerates it, try it once a week at night, then moisturize. Give it a few weeks before deciding whether it suits you. Stop if you get persistent burning, redness, or peeling.
