Thanks for your query
Increased size of skin pores is a common problem especially in people with oily skin.
among the treatment options available for the same, topical application of retinoic acid
containing creams at night helps.
Some degree of improvement is seen on long term use.
If there is not much improvement, you can see a dermatologist
for the same. There are other treatment options like using chemical peels
