It’s overkill. Using a facial masque everyday would dry your skin hella bad.
That’s kind of the point of the movie/book, Patrick does all these things that sounds impressives but in reality are just plain ridiculous
The book is also even more psycho. So many pages, including the original version of the routine, painfully lists out the specific brand and model of a product. Like the brand of their suits and shoes and skincare products, the specific trademark colors of items (:bateman-ontological: bone white), the names of shops and restaurants
