Or I heard that eating meat. Do not eat anything else. So only protein has no carbon.

Skin. Maybe you should wash your face often. You can buy that cheap baby cleanser first. Just recommend a small bag of facial cleanser for you. Tea tree moisturizing facial cleanser, for my own use, is the brand of Gefina. The appearance is green. You can ask which one suits you. I remember three.
