How to clean up the 7 dirtiest places in the body?

In daily life, bacteria and molds are everywhere. Once they have the opportunity, they will multiply in a moist and warm corner of the human body. So what are the dirtiest places in the human body? 1. Concealed nail joints Permeable molds often invade the nail joints, especially the toes and other parts, which usually accumulate a lot of old 'trash'. If they are not cleaned for a long time, they will cause nails to deform and produce peculiar smells. 2. Belly button. In essence, the belly button is the scar left by the umbilical cord falling off after the fetus is born. Careful observation is not difficult to find that the belly button of the human body is a very 'tangled' shape. However, don't think that washing your abdomen in the shower is clean. 3. Behind the ear It is used for cosmetic allergy testing, and massaged when clearing the lymphatic system... This place behind the ear is more useful, but it is not cared about. Especially during daily cleaning and maintenance, I rarely think of it. 4. Elbows and knees This is where you need to focus on removing the thick cuticle. People need to move every day, elbows and knees often perform flexion and extension movements, the skin is rougher and thicker than other parts of the body, and the vertical and horizontal lines are deeper, so it is easier to hide dirt. 5. Nose wing Although it is in the middle of the face, it is under the 'shadow' of the nose. When I look in the mirror, I often see that the area on both sides of the nose that meets the nasolabial fold is red or dull, because this area is prone to accumulate external contaminants and dead skin. 6. Perineum with low resistance. Under normal circumstances, a variety of bacteria grow in the vagina and maintain balance. But because of incorrect living habits, 75% of women suffer from fungal vaginitis. 7. Between sweaty skin folds such as armpits. There may be a large number of molds in the folds of human skin. This is also the reason why obese people are prone to tinea corporis. In particular, the armpits are always wet, and the roots of the armpit hair often secrete viscous substances to breed bacteria. Finally, personal product manufacturers are actively inviting powerful distributors across the country to join in to create wealth together.
