I bought a sebum softener because I'm worried about excess sebum, but I don't know how to use it.

I saw a YouTube video recommending the use of a sebum extractor for oily skin. They said it is much less irritating to the skin because it chemically dissolves sebum, which is an enemy, rather than causing physical irritation. It is an Ingredient Editor product.

But I don't know how to use it.

It doesn't seem to be working as well as I expected... Am I using it wrong? Is anyone else using this? Please share your sebum removal routine.

Also, I'm curious how people with oily skin, especially on the nose and cheeks, cover it up when doing makeup. No matter what I do, it just cakes on me. It's so stressful.
