I have this pimples on my skin and I want to make use of an aloe vera plant in my house. How do I apply,drink?

I am a 20 old male in Kenya. I want to go natural. I do not apply anything on my body as of now. I have oily skin. Now I want to better my skin by bathing with Neem soap and applying aloe vera juice or drinking. How is it done. For drinking do I just boil? Do I just apply the juice on my skin overnight?I have this pimples on my skin and I want to make use of an aloe vera plant in my house. How do I apply,drink?
I wouldnt drink it, its not bad for you but if you want it for your skin then you apply it on your skin. I usually just cut and peel open the plant and rub it on my face. works wonders on scars but it takes a while.
