I just don’t want to mix them because I feel like it would make me less clean.
Relatedly, what’s the best way I can follow the Patrick Bateman skincare routine as a simplified version that’s actually practical to follow and contains the most important steps?
Seems a better solution would be a single, large bath/body towel to dry off the whole body after a shower, that itself gets washed after every use (personally, I wash my towels after two uses). Maybe have a towel just for hair, if your hair is long enough to need it.
Then have separate towels for use throughout the day. A hand towel for drying hands after washing them. A face towel for when you wash your face/brush teeth/shave. And wash those towels and they become soiled.
Using different towels as you just come out of the shower does seem a little redundant and wasteful.
