Re the mud serum.... first off, I do know it's a cleanser, but I don't know if it's oil or water based. It says "oil control" but, like....
Anyway, for science, I did the test: in the shower after a sunscreened bicycle ride, Nivea man oil down the right side and supermarket soap down the left... I couldn't really tell if one was better than the other as far as shifting the greasy sunscreen trail from my person. The Nivea cleanser is a black liquid, which is certainly manly, and it smells funny, but.... so ¯\_(ツ)_/¯
