I have noticed that my foundation and concealer are separating (from a change in temperature it is cold in the room I am putting on and it is hot outside) or that it does not cover what I want. I researched the best tips for people with large pores. I have visible pores in the t zone but not so much in the forehead; however, the front is where I get a lot of the unevenness / separation. The rest of my face is quite beautiful apart from my big pores in my ass that show through. People have recommended a primer but I don’t like using them.
