Is sebum softener effective for blackheads and whiteheads?

As my pores in the butterfly zone got bigger, the blackheads and whiteheads suddenly started bothering me...😭

I've tried the Olive Young Shrek Pack and even massaged with cleansing oil, but there is no change.

I looked it up and it seems like a lot of people use sebum softeners. Do they really dissolve blackheads and whiteheads?

Now that I see it, it bothers me so much that I want to get rid of it completely.

If you have any sebum softeners, other products, or skincare methods that have worked for you, please recommend them to me..🙏
