This is my first post.
I am a sixty-five year old male who has been his wife's hair colorist for most of the 42 years we have been married. I have slightly better taste in women's fashion than she tho' we almost always agree on her clothing purchases. She almost always solicits my advise on cosmetic purchases; and again we most always agree. I am a balls-to-the-wall old school feminist, with a concomitant knee-jerk aversion to anything that smacks of: "Why I believe I am nothing without a man."
I have been reading ingredient labels on everything well before I discovered this web site; and I all I know about organic chemistry is how to spell "organic" and "chemistry." I know even less about physics.
I drilled down to the plain English translation of a recent journal article about some kind of a tubular protein matrix that expands to absorb water and then----unsurprisingly-----contracts to squeeze it out. (I assumed some such mechanism existed to maintain hydration homeostasis.) My question is: why would not this matrix squeeze out occlusives that kept the skin overly hydrated? So for how long do even the best occlusives---I use petrolatum on myself----prevent evaporation of water?
Of course, this begs the more fundamental question: why would anyone man or women in her or his right mind want to tamper with mammalian hydration homeostasis by preventing water evaporation? What are the unintended consequences of skin moisturizing? What body systems are being disrupted by retarding "natural" skin dehydration?
