@hormonespecialist: See any video notes/sources by following the link in my bio. Part 1 of 2 Our next estrogenic is sunscreens. I don't know of any sunscreen with a chemical UV filter in it that doesn't have some affinity for hormonal receptors in the human body. Some of the common ones are benzophenone 3, or BP3, benzylidene camphor 3BC, 4-methylbenzylidene camphor, or 4-MBC, but there are dozens of them. Watch out for the root benz, or phen, in the chemical name. Better yet, just don't use a chemical-based sunscreen. Chemical sunscreens are lipophilic, meaning they're attracted to fat, and we all have a fatty layer in our skin, so a lot of it absorbs right in. It doesn't just stay on the surface. Remember, the skin's an effective dosing route for hormones and drugs applied as creams. So yes, it acts as a barrier and protection from exposures to lots of different things, but to substances with the right properties, your skin is like a wide-open, unguarded back door, and what goes in through the skin dumps right into the bloodstream without being metabolized at all by the liver, like food and other things we eat, which go to the liver first and then into the circulation. It's like getting these chemicals by injection. Yikes. You may say, well, I don't often use sunscreen, so this really isn't an issue for me, but remember, it's in cosmetics, too, like makeup, skin creams, even some soaps. So daily application's a likelihood for a lot of people. Now, chemical UV filters are required to be listed as an ingredient in cosmetic products, but protecting human skin's not their only use. They also protect other materials from the harmful effects of UV light, like plastics, carpet, furniture. DISCLAIMER: THIS SITE/CHANNEL/POSTING DOES NOT PROVIDE MEDICAL ADVICE
