Pretty much title. How is aloe vera gel supposed to be moisturizing when it’s basically water? Isn’t it the same as putting water on your skin?

As with almost anything in, “mostly” X, is not the same thing as X.
Salt water is pretty much just water, but we cant drink it. Similiarly, the to your question answer lies in what is in aloe that ISNT in water.
Specifically, Humectant compounds are one of the conponents in aloe. Normally if you have anything that is wet, the water will enetually evaporate away. It is almost impossible to avoid this evaporation as the humidity in the air is usually way below 100%.
So when you put water on your skin, some tiny fraction might get absorbed, but most of it is going to evaporate, and even the bit that gets absorbed will eventually evaporate as well.
This brings us back to humectants and why they are cool. Instead of letting water evaporate and leave the area (like normal), humectants actually take water from the air. So instead of quickly drying out, aloe will continue to take more water from the air to keep your skin hydrated and moisturized long after plain water would have evaporated.
