Skin is not entirely water-repellent; it has some degree of permeability. The outermost layer, the stratum corneum, contains lipids and proteins that provide a barrier to water loss and help protect against external moisture. However, skin can absorb some water, especially when exposed to it for prolonged periods, like during bathing. Overall, while skin helps retain moisture, it is not completely impermeable to water.

If by waterproof you mean water-repellent, then yes.
It is called Keratinocyte, which is in the outermost layer of the epidermis.
No it isn't water repellent.
i believe that they are not water repellent, but they can tolerate colder temperatures with the help of their mother.
Waxes are a group of lipids that form stiff, water-repellent materials. They are made up of long-chain fatty acids and long-chain alcohols, and are commonly found in plant cuticles and animal skin to provide protection from water loss.
Lamellar granules are responsible for secreting lipids and enzymes in the skin that help maintain the skin barrier function. These granules release their contents into the intercellular spaces of the skin, contributing to skin hydration and barrier protection.
No, not on this site.

Research suggests that leech repellent can be effective in preventing leeches from attaching to the skin. However, the effectiveness may vary depending on the specific product and application method used. It is important to follow the instructions carefully to maximize the repellent's effectiveness.

Polar bear fur is oily and water repellent. The hairs don't mat when wet, allowing the polar bears to easily shake free of water and any ice that may form after swimming :)
