Yeah, I agree. This always seemed pretty obvious to me but it was also obvious that it's nuanced and can be highly variable depending on skin type, medical history, locale, lifestyle and preferences.

But when it comes to things which are very probably "mostly beneficial for most people most of the time - but (obviously) not always beneficial for all the people all the time", there's a reluctance to say anything unless you've got study data to fully support everything you say into "the nines". But the world is full of things that are hard, expensive or impossible to study experimentally with that kind of rigor.
