@lemsip I use Argan/Sweet Almond Oil/Macadamia oil. I buy them in TKMaxx (am I allowed to say that??) - or I do when they're open! Always 100% pure - no mix of glycerins/mineral oils/etc. I have used others as well, but only pure facial oils.
I just mix up what I have - usually about 2/3 Sweet Almond Oil which is cheaper and either put them in a spray bottle or a dropper bottle. A couple of sprays on fingers, rub into skin, then a warm, damp mitt or cloth. Takes makeup off as well, even mascara, but you have to be careful not to get it in your eyes.
