ELI5 how is your skin attached to your face? Actually got my 5 year old daughter.

I like how inquisitive your daughter is. Well, the skin is made of a bunch of cells in a bunch of different layers. At the bottom layer, there is a cleverly named “basement membrane” that is like a sticky protein jello. It literally sticks to your skin cells with a bunch of different proteins that form junctions with proteins expressed on your skin cells. There are a bunch of different types of attachments. Some are like velcro, others are like stitching. On the other end of the basement membrane, it is connected to the rest of your face. Basically, the basement membrane (and a bunch of other connective tissues) does the “tom holland spiderman holding the two halves of the boat together” with your face.
