Do not scratch itches with fingernails under any circumstances. Rub skin with palms. Rub oil into skin. Apply a face mask. Wash with water and soap. Do something else. Do not scratch. Scratching can remove the outer layer of skin oil and damage the upper layer of the skin allowing mites easier access. This makes the problem worse faster. Rub. Don't scratch. Itching is your body's way of telling you there is something wrong. Use moisturiser. Apply a knockdown like rubbing alcohol or alcohol gel. Don't scratch.
