Skin is a semi permiable membrane. Oils, water, and chemicals seep through it in small amounts. This is why people died in the olden days, from applying lead based make up to the skin...from lead poisoning! Also works the other way, as when in water, for a long period, we go wrinkly. Water has seeped OUT of the skin, into the water, of a greater volume, by osmosis. So skin is not water proof.

Moisturiser acts as a barrier to prevent moisture leaving the skin after the oil layer is stripped with cleanser or washing.

To keep the top layer of our skin (epidermis) moist so that it will wrinkle less, a lot of moisturizers act as a barrier to keep that moisture in... my god I sound like an Oil of Olay ad

The moisture in your skin is oil, not water. It's a completely different substance. For this reason, you need to use moisturizer.

If skin is waterproof then why do we sweat? Sweat comes out of our pores. Stuff can get in your pores. That's what causes acne. Or so I think.

It is not 100 % water proof. We actually breath a bit through our skin.

We moisturize to prevent dryness, which can lead to flakes and a poor skin condition.
