No cell membrane is selectively permeable, skin is not...
@Kindofweird look it up. There are little things in our skin called cells... skin cells :)
No... outer layer of skin is keratinized... inner cells are living... they are selectively permeable...
@Kindofweird Then explain why we use moisturizer and other fat-soluble lotions on our skin if it isn’t selectively permeable. The skin behaves as a selective permeable membrane only allowing certain substances through. The outermost layer of our skin is made of keratin (dead skin cells); however, the membrane is selectively permeable. There isn’t enough space for larger molecules to passage through the density of the membrane, but smaller molecules can still pass through making our skin selectively permeable.

What kind of soluble humans do you know? 😄
The article states: “For reasons that still aren’t well understood, human skin starts to break down after continuous immersion in water”. This is due to osmotic lysis. Cells burst when excessive water diffuses into them and aquaporins can’t dispose of it quick enough. If you put an animal cell into a hypotonic solution, water rushes into the cell and eventually kills it.
@BeMuse thanks! I thought saying that I’m the article sounded more like someone who didn’t want to do more research.
Yes? Though they do plump up nicely if left in water 🤭
Then I'll tottle to yes
I fucking knew it!
I am the night!
