2-in-1 products: I say this because tons of products marketed toward males have this ‘nifty’ little feature that is good for no one. If you wanted to get a cleanse + exfoliate type of product to just use daily, you would just be doing more harm than good for your skin. Since you get sun everyday + facial hair grooming (however often you do it), treat your skin as if it were sensitive even if you don't see any redness or inflammation. Separate products are better so you can balance how often you are doing each step.
Pore strips + peeling masks: products like the Biore strips or peeling masks that remove blackheads are good in a situation if you are going to an event and want to style on the crowd with a fresh face. But overuse (daily or even weekly) will just make the pores on your face larger over time. Which will just make blackheads and whiteheads more visible.
Foaming anything: products that foam have a lot of alcohol so it just dries out the skin overtime. I don't even understand why they're made.
It's OK to
Ignore some directions: I’m thinking about exfoliators again because people tend to over do it. Even if a product says it is ok for daily use, it is not. It’s too much! Very harsh on your skin especially after the sun.
