Ifound a way how 2 cure pimples zits i dont know about acne tho but i can cure my pimples and stuff

If you don’t have bad acne and just have a few zits and pimples, try spot treatments, washing and exfoliating your face, and moisturizing. There are many different ways to help with acne, but you must know your skin and how it reacts to different treatments. Take into account how dry your skin is normally, if it’s oily, if it’s neutral, etc. Think about whether or not you need something for sensitive skin, tough skin, or some other variation. Make sure you don’t have any allergens. Once you’re almost sure that a solution for your acne is safe, try it out!

Ican only answer your first question, a machine is like a human body because it's a little similar. they both almost work like the same.
