When Aloe Vera is ingested it treats the digestive and immune system. When it's used on the skin it only treats the skin

I used the gel on my skin after radiotherapy.It be very soothing.Some those use the aloe vera drink for their digestive system.
I think direct application on the skin would work faster and better.
