What makes something waterproof?

Answer 1

Something that is waterproof is resistant of water and will allow the penetration of water or moisture. There are many types of items that are considered waterproof such as cosmetics and skincare.

Answer 2

Skin is actually composed mostly of water as is the rest of the human body. If you've ever been in a pool, ocean, or other body of water for a long enough period of time you'd notice that when you got out your skin had become "pruned up." That's because the skin absorbed water.

Actually, it may be that skin is made to hold in water in the right amounts for us to live. and also to keep water out so we don't become waterlogged and drown

Also, your skin is composed of 3 layers. The epidermus, the dermus, and the subcutaneous fat. The dermis ( being the second layer) contains something called sebum. Sebum is a natural oil, it keeps skin lubricated and protected.... and also waterproof. As long as your body continues to produce sebum , it will not absorb dangerous amounts of water.

Answer 3

There are actually three things which allow skin to be water resistant. And yes, I do mean resistant, not proof. If it were water proof, you wouldn't get all pruny after spending too much time in the bath.

The first factor is naturally occurring oils in the skin help to repel water, preventing it from sitting on the skin and being absorbed in the first place.

Second, skin itself is actually a net of tissue, so even if water permeates the first layer, it has a harder time getting to the second. If it gets to the second, it has an even harder time getting through the third, and so on.

Three, cells in your body already contain a high percentage of water and will not absorb much more (unless yoru skin is very dry or you are very dehydrated), so like trying to fill an already full bucket, the water just runs off. Skin cells make ur skin water proof u dunce keratin

Answer 4

It is the oil gland in your skin because it helps keep your skin soft and it also makes your skin sleek enough for the water to just roll off your skin like it does on a leaf.

Answer 5

The skin itself is the waterproof layer for your body. The oils produced by your skin make it water resistant.

Answer 6

The natural oils the your body produces.
